This was a gift from a student, and I love it very much. But there are some problems, mathematically speaking. (See 'em?)
And, anyway, 6 times 2 isn't nearly nerdy enough.
Here's what I figure: I've got a can of blackboard paint in the closet, and I can remake the clockface for mathematical correctness and interest.
But what should I put for 1 o'clock? For 7 o'clock? Midnight/noon?
You'll help me out with this, right? In the comments?
