This is interesting, but not good for more than a few minutes (it gives you 10 tries, and it's so tiny on my monitor). Does anyone know of something similar that is more involved? Commercial software maybe? I'm sure something good must have been programmed in Flash by someone. I have a little boy who memorized all the states about 6 months ago and I'd like to see how much he's retained without taking him back to the big blank map.
