Yenn’s “Skew Tetrahedron” and “Stand in The Corner of The Desk Drawer Box”
- Posted by admin at 16:19:03 // //
Thanks to the “calendar” feature over on the homepage of the Origami Database, I discovered that today is the anniversay of Thoki Yenn’s birthday. It seemed fitting to go fold something by Thoki, so I popped over to the BOS website and hunted up their archive of Thoki’s old site. (http://www.britishorigami.info/academic/thok/index.html)
I picked two somewhat random models that I’d never folded before, and here they are.
The box is pretty cool, it’s basically a cube but with one vertical corner chopped off (so as to take up less room in the drawer, I’m thinking.) Fun shape, though.
The tetrahedron is very odd - it’s the shape you get if you cut a tetrahedron along several diagonals at once (i.e. the edges are 1, 1, sqrt(2) and sqr(3). Apparently its volume is 1/6th that of a cube - if you make a total of 6 of these, 3 “right-handed” and 3 “left-handed” (i.e. the mirror images of the first three) you can put them together into a cube. (Thanks, Scott, for the pointers!) Very cool.

Needle’s “Snowflake”
- Posted by admin at 16:00:31 // //
Jared Needle mentioned on the O-list that he and Andrew Hudson are doing a sort of advanced-origami-weekly-calendar, online at http://origamiweekly.blogspot.com. I wandered over and downloaded the crease pattern for the snowflake (wasn’t in the mood for a snake, sorry Andrew!)
I’m not much for folding from crease patterns - though given the amount of stuff that’s getting published these days that way, I figure the practice is good for me - but I did manage to get a version of the thing folded, over several tries. (Crease, try to collapse, fail, unfold, repeat.)
Yay!
Definitely one of those “and then a miracle occurs” folds, you just have to pre-crease everything and then fold it all mostly at the same time. Heh.
This is folded from a synthetic drawing vellum.
