Here, I fold six US dollar bills into the modular origami model "Umulius Rectangulum" designed by Thoki Yenn.
The model is also known as the magic rings, impossible rectangle, Umulius Rectangle or even "Borromean Rings": three rings linked in a way that by removing any one ring the other two aren't linked anymore, either.

Actual folding time: 40 minutes
