I honestly don’t even really understand what I’m looking at. But it’s amazing.
More inspiration from the terrific MoMath talk by Erik Demaine on Math and Origami: during some explorations of the one-cut problem, a student produced this, which we all agreed was beautiful.

A Klein-bottle hat (seen at right)? A Mobius scarf? Ingenious stuff, and a testament to our unlimited creativity and resourcefulness, if not our practicality.

The author of the blog post, George Hart, is the proprietor of the soon-to-be Math Museum, and it seems he is something of a sculptor himself. According to the article, this piece was on display at a conference held by the European Society for Mathematics and the Arts.
Poking around their website and admiring the the multitudinous mathart is a pleasant way to pass a little time.
