Remember typing class in school? Remember having to type really boring phrases that the teacher gave you over and over again? Although there have been many attempts at making learning typing more fun (Mario Teaches Typing, anyone?) I think this program has finally nailed it on the head. Arcade Typing Tutor is a Space Invaders-like typing program, where the words are various space junk hurdling toward you, and as you type the word correctly, the object is shot with a laser.
