Me too! We've been having fun with it (though I think DD is going to age out of it really soon, but that's okay, I'll just donate it to the local homeschooling resource center).

It also reminded me to show DD moebius strips, which she was gratifyingly blown away by.

Klein bottles are even more fun that moebius strips.
