Yes, very neat! That story mentioned something other than the Menger sponge, called the Mosely snowflake sponge (I think), which Jeannine Mosely also organized the construction of at USC. I would love to learn what this is, mathematically. But I haven't been able to find any such description on the Web. There is a webpage about how it is constructed out of business cards. (I'd rather not try to reverse engineer it from that.) Anyone know what it is? Sounds like a 3D version of the Sierpinski (?) snowflake curve. The most obvious version of this has been well studied (and has convex hull equal to a cube). So I suspect it's something else. --Dan On 2013-01-22, at 5:11 PM, Michael Beeler wrote:
