935: Snapology Icosahedron

| wonko

I have seen amazing geometric models based on Heinz Strobl’s strip-based modular technique called “Snapology”, and thought it about time I gave it a try:

Starting simple, I divided A4 sheets lengthwise into eighths, then gridded squares on those strips. I used grey for the core, 6×1 strips were cut for each triangular core. I used red for the connectors – 4×1 strips were cut for these.

The locking mechanism is simple, and in situations where the modules are tightly packed it just sort of holds itself together, but I can see how, with small extensions to the connectors you could easily and securely lock adjacent modules more securely. Continue reading →

934: Mikiller觅晨’s Modular Dragon

| wonko

Assignment time at school is fairly boring, for the most part, for a teacher. Students have lots to do, you need to be available to help on demand but there is a fair bit of sitting around waiting to be needed:

I had found a bunch of PDF’s explaining briefly how to fold parts of what I had assumed would eventually be a dragon. After trial folding the head and a foot I thought it was something I could do in stages. I (arbitrarily) decided my “standard square” would be the biggest cut from an A3 page. Most parts were then made using this standard.

Origami purists would probably have issues with this design, as there is an element of paper craft in some of the details, the head, for instance, is actually 1 standard square and 6 other bits of paper, folded and (shhh) glued in place. The body was made from 7 separate standard squares, 6 of which were the same, the tail segment was a little different to create the fan end.

929: Penrose Triangle

| wonko

I love geometry that messes with your head, and a “penrose triangle” is a faux 3d shape that is clearly impossible as a whole:

Looking at any 2 adjacent vertices, it looks fine.  The twist of dimensions is what makes it difficult for our brains to comprehend. Continue reading →

928: In Memoriam – Francis Ow

| wonko

The international origami community recently learned of the death of Frances Ow:

Francis was an active and beloved member of the Singapore Origami group, and sadly I never had the privilege of meeting him in the real world. But, via the magic that is the Internet I have been personally encouraged and supported by him over both of my recent 365 challenges. You can try this Tsuru Wreath for yourself – one of many designs he shared freely. Continue reading →

916: Zhen Xian Bao (Traditional Chinese Thread and Needle Book)

| wonko

Interestingly, paper folding developed independently in most countries that made paper. In China, traditional folding included objects like this:

This is a modern interpretation of a Zhen Xian Bao – a traditional thread case. Even cursory research on teh interwebs reveals astonishing combinations of these little compartments, nested in other compartments.

This fold was designed by Paula Versnick, and has 7 separate compartments of varying size, that all lock together into a charming little book. Continue reading →
