[Origami] (Brief) Origami sighting

[Kevin Lee]

Hello
Numberphile, a math based Youtube channel with ~1.3M subscribers, recently did 
an episode on Klein Bottles, with Cliff Stoll.08:22 in, he reaches to his wall 
and picks up an origami Klein Bottle (https://youtu.be/AAsICMPwGPY?t=432)
Apparently it's a design from an exciting new origami design talent, Dr. Robert 
Lang.Anybody ever heard of him?
Yours, with tongue firmly in cheek,K Lee
