blinryI made a pop-up card that spins as you open it!
It uses a geometric mechanism invented by an unknown student at Musashino Art University in 1988! Instructions here: http://www1.ttcn.ne.jp/a-nishi/popup_spinner/z_popup_spinner.html
Another surprising result from computational origami: If you fold a piece of paper correctly, you can cut out arbitrary shapes with a single, straight cut! Even multiple ones! This is possible for all shapes!! :O
Könich Henry📯@blinry Enterprise-D or didn't happen!
@blinry Wenn das geht bin ich richtig baff, denn das wäre ja ein Shape mit konkaven Ecken.
@harrysonsan Maybe this turtle is close enough! :D http://www.science.smith.edu/~jorourke/HowToFoldIt/Turtle1-Cut/FoldingTheTurtle.html
@blinry Nope! Keine Enterprise, keine Schokolade!
