I'm happy that Race Track is there (in Other)! It's like a super minimalistic version of Car Wars, but still very fun. You get the same realization of "Oh shit, I'm going too faaast!" when you're about to lose control.
I also remember playing this! We also had an alternate version where you place your pen vertically at some point and then push down on it so that it slides in the desired direction. The end of the resulting ink trail is where you start your next turn. Of course it's quite possible to crash into a wall if you're not careful.
We used to play it all the time when we were teenagers, in class of course :). It's got some nice (simple) vector math going on. Can't wait to teach it to my kids.
