I like arts and crafts, particularly those with a mathematical bent. Wholemovement – The Work of Bradford Hansen-Smith shows what cool stuff you can do with paper plates. Be sure to read the commentary about the “wholeness of circles” and the like. I’d like some of whatever he’s smoking. Found this while perusing the terrific Geometry Junkyard, which I noticed now has an RSS feed. I’ll be adding it to my list shortly.
