Can the Same Net Fold into Two Shapes?

Video Description

If you cut out the net from the card and solve a fold: send me a photo! Maybe hang it on your tree as a decoration. To receive a physical card you officially need to be a "statistically significant" supporter (or higher) on Patreon by the end of 06 December 2022.

You can see their page (with all 2263 nets) here: http://www.jaist.ac.jp/~uehara/etc/origami/nets/index-e.html All the publications I waved around: 2007 - "Geometric Folding Algorithms" by Erik Demaine and Joseph O'Rourke 2008 - "Polygons Folding to Plural Incongruent Orthogonal Boxes" by Ryuhei Uehara 2011 - "Common Developments of Several Different Orthogonal Boxes" by Zachary Abel, Erik Demaine, Martin Demaine, Hiroaki Matsui, Günter Rote and Ryuhei Uehara 2013 - "Common Developments Of Three Incongruent Orthogonal Boxes" by Toshihiro Shirakawa and Ryuhei Uehara 2015 - "Common Developments of Three Incongruent Boxes of Area 30" by Dawei Xu, Takashi Horiyama, Toshihiro Shirakawa, and Ryuhei Uehara Here is Geometric Folding Algorithms on Amazon if you want your own copy to wave around. But it costs 'text-book money'. https://amzn.to/3OYDXrF Huge thanks to my Patreon supporters who funded those crazy nets I was sticking together. Support me and help me make more ridiculous shapes (also: videos). https://www.patreon.com/standupmaths CORRECTIONS - At 07:36 I place the top shape in the wrong spot. But it totally works! Look at the diagram! - Let me know if you spot anything else! My bad taping skills do not count as a mistake.
