Another Cellular Automaton experiment. The rules for this one work as follows:
0. Place an ant on a grid.
1. check the color of the square the ant is on.
2a. If the square is red, turn it black and turn to the left.
2b. If the square is black, turn it red and turn to the right.
3. Move forward one square and repeat.
No interaction here; it will do the same thing every time you visit.
If you are patient, some interesting things begin to happen around iteration 10,000.
