If you need to ask, I'm a teacher who has a student teacher and I found myself with some time on my hands.
The first one was the Fuk-U-Meter, and I actually made it, but then reconsidered. This is version 2.0. The numbers are in Japanese and are authentic as well as interchangeable. I also tried to do the Japanese flag with the Cubs logo.
Look for the Fukudometer making its debut this Saturday in section 529, row 1 (upper deck, on first base).
