Roller Paint     Added: Monday, June 16th, 2003     What kind of idea: borrowed
	I got this idea from Keith - He suggested just taping a motor and wheel to a roller to make it go. I used two motors and two wheels, because I wanted to be able to control (at least a little) how the machine turns. It is hard to tell in the picture, but it draws big arcs (In the program, I set the motor power at "1" for one motor and "2" for the other). And it runs out of paint pretty quickly, but it was fun to have something that could draw on a huge piece of paper on the floor.
