Dollar Origami Tutorial: Impossible Rectangle "Umulius Rectangulum" aka Magic Rings (Thoki Yenn)

Paper used in this video: $1 bill
Finished model: width of 7 cm or 2 3/4 in

This video describes how to vary the folding sequence for the origami "Umulius Rectangulum" designed by Thoki Yenn, so that you can fold it from US dollar bills. That's right, it's money origami, or moneygami!

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.

Thomas S√łndergard, son of the late Thoki Yenn, kindly gave me permission to make this video accessible to you.
