I also put up a small page on Sierpinski's Tetrahedron. I'll be leading a workshop where we make a large one at the BRIDGES conference in two weeks. But first, I'm off to Paris to speak at the ESMA conference!

To get a sense of the kind of wonderful things he's inspired, check out reports from this year's Gathering for Gardner, such as this article by Bob Crease in The Wall Street Journal, or more recently, this one by Alex Bellos in The New Scientist. The building of the balloon snub dodecahedron mentioned in that article is shown at right, and the print version of contains a rather large picture of myself holding a balloon octahedron in front of my face.

I also spent the day making magic balloon octahedra for people. Here are some pictures from the event:

I will be twisting balloon octahedra for children of all ages at the Math Midway premier next Sunday (June 14th)! There is a small green one in the photo, but I can make you any color you like.
