Short-Beaked Echidna

There are only a few origami figures I MUST have in my collection – Steven Casey’s “Echidna” is one of these:

This adorable little monotreme is covered in one of my favourite square-grid tessellations, but skillfully crafted to allow all the other body bits to be where they need to.

I bought the British Origami Society booklet describing how to fold this treasure as soon as I knew it existed, and have folded it a few times now. Some sequences are nightmare fuel – this one is just so enjoyable to fold.

I recently received a shipment of paper from Origami-shop.com and in it was a 65cm 11 colour pack of the NEW Shadow Thai paper. I last bought it in 40cm square form but it was THICK so to my delight this version is thinner and takes complex folds really nicely. I chose this fur-like colour because it most closely matched the quill and hair colour of an echidna.

1142: Daniel Brown’s Seamless Chessboards

Having folded Steven Casey’s 8×8 40 grid seamless chessboard and singularly failing to fold Marc Kirschembaum’s 40 grid because of crease-creep inaccuracies, I was approached by Daniel Brown and asked if I was interested in his chessboards – naturally I jumped at the chance. “Seamless” chessboards are deliciously more complicated because it required each square to be represented by an un-broken surface (as opposed to being able to be comprised of bits and pieces of layers – a much easier path):

A "clusterfuck" of seamless chessboards
A “clusterfuck” of seamless chessboards

I say CHESSBOARDS because Daniel has developed a series of coloured/white alternate seamless models of LOTS of sizes, and the skills necessary to migrate edge paper towards the centre to effect colour changes is a thing that needs some work and, often, particular “widgets” (or self-contained localised fold structures).

I started with the 4×4, rather efficiently designed on a 9×9 grid ( 0.444 efficiency). I had a piece of blue-white kami, so gave it a whirl. Even dimensions require different approaches for adjacent corners as they are different colours – the same colour corner exists on the diagonal.

8OSME – Melbourne, July 2024

An unmissable opportunity presented itself where both OSME and Folding Australia conferences were to be hosted in Melbourne, Australia, one following the other. Having never attended an Origami conference (of any flavour) before, I jumped at the chance, but had little idea, really, what was ahead.

Diverse plenary lectures to start the days off

My wife and I got an Air BnB on Collins street for the week. Using the PT> train network, I travelled to and from Swinburne Uni for the international gatherings each day while Jo explored Melbourne Galleries and cafes.

I believed OSME stood for Origami, Science, Mathematics and Engineering – turns out the “E” was for Education, even though in this conference there were 2 Engineering strands … so, ok then. It seems the 8th iteration of this conference reflects origami/folding now so popular as an engineering concept.

1139: Quantum Superposition

Schrödinger’s Cat, as a thought experiment, states that if you seal a cat in a box with something that can eventually kill it, you won’t know if the cat is alive or dead until you open the box. So, until you open the box and observe the cat, the cat is simultaneously dead and alive.

We often use Schrödinger’s thought experiment to explain the concept of superposition. The experiment states that a hypothetical cat is locked in a box with some radioactive substance controlling a vial of poison. When the substance decays, it triggers a Geiger counter that causes the poison to be released, thereby killing the cat.

Since the box is locked, and we on the outside don’t know whether or not the radioactive substance has decayed and released the poison, we can’t tell if the cat is dead or alive. So, until we open the box to know for sure, the cat is both dead and alive. Mathematically speaking, there’s a 50 percent chance the cat is dead and a 50 percent chance the cat is alive. Source.

This is Sebastien Limet’s Shrodinger Square, a delicious exercise in folding a figure then hiding it inside another structure. I folded this in baking paper, and it is a little too transparent I think (I tried it in printer paper and it was too thick and opaque).

I like that the cat is made of the body and tail at opposite ends of the 5:1 sheet, closing and locking it brings the two pieces together in silhouette. Clever.

1137: Crane in a Box

Cruising the channels on Origami Dan, I found a CP for a fold challenge I had missed, but decided to give it a whirl anyways:

Designed by Scott Okamura, this seemingly impossible fold featured a traditional Tsuru (crane) folded in the middle of a large page of duo paper – the surrounding paper is then formed into a box.

1136: Tsuru-Jin

As lightning crackled from the raging thunderstorm above, the electrodes sizzled, the smell of burning flesh hung damply in the air as the creature stirred on the table, accompanied by a mad cackling laugh interspersed with hysterical cries of “It’s Alive!!!”:

Apologies to Frankenstein lovers, but let us face it, this model is a bit of a Frankenstein. It is the result of putting a Satoshi Kamiya RyuJin 2.1 dragon head on a classic Tsuru (Crane)’s body. Nuts – right?

I first saw the CP (Crease pattern) for this on one of the Origami Discord servers I frequent (RyuCentral), and thought … how odd, how hard could that be??? Stupid man!

Dividing the paper into quarters and half along one diagonal, I reserved 1/4 on the diagonal for the crane and then set about laying in the graft CP for the dragon head in the remaining 3/4. It needed a 23 division grid that intersected at the square opposite the crane. Accuracy was the key. Grid laid in, I then started setting the pre-creases necessary for the head – stupid man, fucked the first set up twice (because I did not count), finally, pre-creasing done the collapse began.

I have folded many Ryu Jins, many versions, many times, so it was like returning to an old friend, interestingly muscle memory helped me not find the horrendously complex manipulations difficult at all (or maybe my subconscious was blocking the trauma) but to my surprise the accuracy I obsessed over early on paid off later allowing a pretty tidy collapse and NO damage to the reserved 1/4.

With the head collapses through early base, late base and shaping, I isolated and shaped the little arms and then set about working out how to fold a crane with the head as the head. Annoyingly I chose the wrong orientation first (der) and the head was upside down and backward. Just when I thought I would have to perform an infamous “neck twist” (interestingly NECESSARY on full RyuJins), I tried unfolding the crane and reversing all the creases (ie. folding it inside out) – to my delight that solved the problem (and THEN I remembered CPs are usually drawn WHITE SIDE UP – what a dickhead!!!).

Square Field Crumple

I bought some new shirts yesterday – interleaved inside was some lovely white tissue. I folded it into 3rds, then half to get a square, then half, then half and kept going until I had a small, multi-layered square about 8cm on the side.

Next I crumpled that so the centre of the square was a point. It was tough as there were so many layers. I then opened the last halving, reinforced the valley between, inverted one of the points (as one was up, the other down), and re-crumpled the points.

Repeating this technique, opening a layer, reinforcing the valleys in-between each point, inverting half so they all pointed the same way and re-crumpling, allowing the crumples to become more random as they thinned out.

1102: The Offering

Tucked away in an inconspicuous corner of the deserted clearing, nestled almost invisibly among the leaf litter, the first signs of civilization were found in the form of a rough-hewn but definitely hominid-worked paper offering. For whom, to what, why … we shall never know:

Followers of the blog will notice occasional references to paper making pursuits. This post looks at the most recent results of a paper making workshop I attended in early July 2023. I had previously (back in 2019) been a member of PAQ (Paper makers and Artists, Queensland) but found full time work made attending events difficult. Now I am retired I have more freedom, so reapplied for membership.

The group’s interests in paper are diverse – from botanical paper making, monoprinting, encaustics, stitching, collage, pulp sculpture and more – my interests are (fairly narrowly?) folding, but it is important to have ones interests informed by a wider palette so I am very much the learner in that group.

Previous workshops I made sheets with finely beaten banana stem and cotton display board, day lily and lemongrass pulp, and still have some of the paper from that session. This session we pulped banana stem (coarsely this time) and mixed it with lemon grass, Philodendron, and South African Pigeon Grass stem, in various combinations. The pulp was added to water, then a suspension-aid made from water soaked chopped okra, which generates a mucilage that makes the vat water more goopy, helping the pulp to stay in suspension longer before settling out. The results were much coarser paper, but it presented an interesting challenge to see what I could fold from it.

I first pressed then dried my sheets, brought home still dripping. I carefully separated them from their couching sheets (old torn up bed linen) and selected sheets to process further. Using a fairly stiff batch of Methyl Cellulose, I stuck sheets to my glass and let them dry, reasoning (correctly it turns out) that the MC would make the sheets more pliable and bind the fibres more closely together (given some of them were very loosely bound, this seemed like a good plan).

1098: Dumb and Dumber

I love a clever conceptual fold, and “Emptyhead” designed by Boice Wong (origamibyboice) is a clever example of art designed to make you think:

The first of these models – “Emptyhead I” is a lovely character that has an empty box sitting on his shoulders for a head. This model, uses a variation of the original CP (crease pattern), and represents his dumber brother completely detaching his head from his shoulders.

The original, as folded by Boice, has a solid cube for a head, but I Macgyvered a scheme to make it an open 2x2x2 cube instead, so he is clearly related to his more sensible brother.

From a 32 grid, this model cleverly presents shoes, cuffed pants, dress shirt, tie, collar, overcoat with lapels, 1 regular arm and one extra long arm, part of which becomes the box head. Such a neat design, the paper cleans itself up and provides wraps to make the seams tidy on the arms also. All this with no cuts, folds only. I did resort to using a few white glue spots to keep seams and layers in place, but tried to keep it as au-naturel as it was possible while being able to pose him for archival purposes.

I must admit to obsessing about this version, having solved the CP for the first version fairly quickly (which really surprised me if I am honest). I just assumed this version would let me make the free box head, but as I discovered, turning the long pleated tube into an open-ended box, when there was so little paper was a major issue.

1097: Jetlag

Those who know me realise I am just back from nearly 7 weeks in Europe. When asked how my jetlag is going, it is difficult to put the answer into words:

Spending so long in a different time zone, and getting good at waking early, being on the go to many and varied locations, then being subjected to 29ish hours transit to return to the other side of the planet is always a struggle, but this time it seems to have been worse. Bouts of fatigue followed by being wide awake at 3:30am are exhausting, as is my numb and seemingly empty brain.

This is my test fold of a new Boice Wong design. Boice is a crazy talented origami designer who released 2 versions of this model while I was overseas. He graciously released the CPs (crease patterns) and … they did not look too hard … but have taken nearly a week to decipher with my head in it’s current state.

Entitled “Empty Head 32×32 grid”, this is the first of 2 models in this series I intend to try, and feel a little guilty using up a blog number on the test fold, but I am so happy with how this little guy turned out I thought why not. When I have both figures, I will post again using a new blog number.

1093: “An Origami Journey”

Avid noticers of this blog will realise that, since 2011, I have been rapidly expanding my abilities as a folder. Like most people, my first ever origami experience (apart from largely unsuccessful paper planes) was an origami crane (Tsuru) – taught to me as a boy of 11 yrs by a Japanese exchange student. A few years back I completed my task of learning how to fold Satoshi Kamiya’s “Ryujin 3.5”. This fold is not unrelated to both events:

Brandon Wong's "An Origami Journey"

Crane to complete Eastern Dragon is quite a journey, learning all sorts of new techniques and refining skills along the way and this fold celebrates that very journey. Originally designed and folded by Brandon Wong (@ThePlantPsychologist) – I first saw his fold on Instagram, and then photos of it on OrigamiDan (a discord server I am a member of) and vowed, one day, to fold it.

Brandon very kindly published the Crease Pattern along with photos of his fold, and right now I am rapidly learning to solve crease patterns so the perfect storm emerged after retiring I have time to tackle more ambitious folds.

Brandon Wong's "An Origami Journey" 360 view

After gridding the 90cm square, I set about laying in the exacting additional creases needed, including a puzzling pythagorean hinge line and some baffling level-shifters. Collapsing was a …. process. Apparently I “parachuted” the model – starting at the edges and working towards a bulging centre is termed parachuting (which is something I must address) until it more or less sat flat. After checking in with Brandon (isn’t the internet amazing) he suggested a fix for the only collapse kludge I had on his right shoulder.

1089: Caiman

A caiman is an alligatorid belonging to the subfamily Caimaninae, one of two primary lineages within the Alligatoridae family, the other being alligators:

Caiman

When is a Crocodile not a crocodile – when it is an alligator, apparently.

This model has taken me an age for a number of reasons. The model, a genius design from Jeong Jae II (taken from the book “Origami Pro 6 – Wild Amazonia”) has over 300 diagrammed steps (worse, many are “repeat x-y, in reverse upside down”) and every part of the square is worked, then re-worked in many and exacting ways. I wanted to understand and enjoy the processes I was performing and some of them took time to do precisely.

Not rushing to “set” a crease is an important tenet here – until the crease is set there is still time to change it, once set it is permanent damage to the sheet – I tried really hard to set the creases in the correct place.

Caiman views

Scaled/pleated models always fascinate me – the design strategy behind HOW these are designed are completely beyond my comprehension – pleats and scales take a LOT of paper, so planning what is done and where is exacting. Following the set of instructions is complex enough but there are some who could fold this monster from a crease pattern (CP) alone – but not by me – that still is beyond my ability.

A quality design looks good with folds alone – and when I had laid in all the creases and roughly shaped it, the model was already wonderful. I did a little bit of cleanup – closing gaping seams with spots of glue, closing the underside of the tail to give it volume and wires in the legs for permanent posing. Remarkably little was needed to make this presentable.

1080: Invention of the Crane

This is a very personal fold, as well as a lovely meta design:

Boice Wong's "Invention of the Crane"

The first thing most people learn when they start out in Origami is the traditional crane. This fold speculates the genesis of this model as a happenstance some time back in the mists of time. Interestingly, the first model I was taught, as an 11 year old, by a Japanese exchange student, was the crane.

Designed by Boice Wong, released as a crease pattern, I was decided to give it a whirl. If I am honest, I am not really happy with my first fold, and will probably attempt it again (having learned heaps in the folding). The CP can be found here: https://www.obb.design/cp#iocrane

Using a single square, no cuts, we have a lady in a traditional kimono, kneeling in front of a low table on which there is a single crane. The genius of this design is the model is complete – it looks finished all the way around (indeed I fashioned a lovely “bow” Obe at her back. There is a colour change making the table/crane a different colour to the girl (I decided the focus of this fold was the crane, so it ended up white – next time I might just paint it, or perform an additional colour change which is possible with this design but results in a clumsier crane I think).

Boice Wong's "Invention of the Crane" Views

This has taken me an age. Initially, I attempted to collapse the base only to discover it was inside-out, then trying to sort out what flaps did what job (kinda aided by sorta advice from Boice himself), and decided on the current flap assignment when trying to ascertain how to compose the kimono and hide the internal layers, yet still give me the hair fringe. Quite a wrestle in the end.

1075: Nessie

I am constantly surprised what you can do with the classic bird base:

Peter Buchanan-Symons' "Loch Ness Monster"

This is Peter Buchanan-Symons’ “Loch Ness Monster”, a fascinating exercise in colour change and tight accordion pleating that takes the points of a bird base (traditionally 2 wings, a head and a tail) and manipulates them to make 4 stickey-uppey colour-changed flaps that are then bent to produce a familiar outline.

Peter Buchanan-Symons' "Loch Ness Monster" scale

This is a simple model from a forthcoming book “Folding Fantasy Volume 1” that I helped edit – some lovely challenges therein.

1069: Starlight Kusudama

Each year for the last 10 or so, as part of the “getting to know you” phase of a new year with my pastoral care group, we fold a kusudama together:

Starlight kusudama construction

The idea is simple, invite kids to sit, learn how to fold a module, then teach it to another mate … resulting in enough modules to assemble a megastructure.

Starlight Kusudama finished

This year I chose a 30 module designed by Vladimir Frolov, a Russian designer, a lovely starry ball.

The metaphor is really simple: “The WHOLE is greater than the SUM OF IT’S PARTS”
