Here's a typing practice program that looks fun. I often want to get to where I stop looking at the keys, and enjoy a bit of this sort of practice.
I suppose I could put this one on Math Mama, but it seems more at home here. It's art with a political statement called Running the Numbers. The first one looks like a Charlie Brown picture until you get close enough. It "depicts ten thousand dog and cat collars, equal to the average number of unwanted dogs and cats euthanized in the United States every day."
