Pi Clock

I make it a point not to talk about my work on this blog. There are other forums in which I engage in work-related discussion. However, I will mention that I am currently working on a project that involves the unit circle. So I was delighted when Laura told me about this site, where one can buy all sorts of geeky, math-related items. (This is even better than ThinkGeek, which markets more to the computer nerd. Guess where I go to get gifts for my brother Joe?)

Back to the unit circle ... I was thrilled to find the Pi Clock. I haven't bought one yet but it's on my wish list. The best part is that you can get the manufacturers to adjust the mechanism so that it starts at 0 radians (3 o'clock position) and goes counterclockwise.
