793: (243/365) Jun Maekawa’s Tetra tetra

Looking for today’s fold, I returned to a collection of bookmarked models from my growing collection of Tanteidan magazines:

Made of 4 tetrahedral modules, each with deep tabs along a pair of adjacent sides, you then fold a pair of interlocking preliminary bases as the core. Continue reading

661: (111/365) Multiple Rippling Deltoid

I have passed this model many times, thinking “not sure what that is, maybe later”, but decided to give it a whirl tonight:

What a curious object. Designed by Jeremy Schafer, from his book “Origami to Astonish and Amaze”, this odd ripply mathematical conundrum hurts your brain to look at.

A fun paper manipulation first makes a nested tetrahedron, which is then accordion pleated to make the deltoid. You can then open it up like some surreal book, 4 separate rippled deltoids emerge – curious indeed. Continue reading

615: (65/365) Spheroid

Who could have foreseen that the concurrence of a series of parallel mountain folds interspersed between a series of concentric parabolic valley folds would result in something with such sculptural simplicity?:

This is Jun Mitani’s “Spheroid”, well, at least as close as I could get to it by guessing the intervals between parallel lines and the curve on the parabolic ones. Continue reading

Numbers? What Numbers?

I am often asked why some of my posts are preceded with a number. I must admit to folding paper, on and off, since I was 11, but more recently I took it back up again as a sort of physical therapy to convince myself (as much as anything) that I could control my nerve-damaged hands after spinal reconstruction.

The numbering makes sense to me, really. On January 2011 I (in retrospect rather naively) decided to try and fold a different model every day for a year. I numbered the models as I folded them, using that index to catalogue the unique folds I managed to achieve.

When I got to 365, I ran out of 2011 and no longer had the one a day madness that was actually really interesting.

I decided to keep folding. When I fold something I had never folded before it too is granted a number. I will continue Рit is a useful metric for me, might be an organiser for you but it reminds me of the staggering variety of models out there, and reminds me of the fact that I have really only tried a tiny fraction of them so far.

Now you know …

500: Jackass

To celebrate the 500th unique fold documented on this blog, I thought I would hold a guessing game whilst trying a fold I have been considering for a while.500JackAss

This is “Horse Laugh” by Kunsulu Jilkishiyeva from Nicholas Terry’s “Drawing Origami Tome 1” – a fun fold that sees some amazing box pleating and layer management to make a really detailed head (with lips, teeth, eyes, the works), tail, rather lovely mane and some funky legs. Continue reading
