Metamorphosis, by Andrew Hudson
One last diagram for 2009... this is a Flexagon I designed last october during the Octagons for October challenge at the Origami Tessellations group. I was inspired by Yami Yamauchi's Fireworks modular, and set out to replicate the effect with a single sheet of paper.
The model in the video was wetfolded from 10" x 20" Canson Colorline paper, colored with various spraypaints. Diagrams are here.
