From Wikipedia:

Squares on a plane are colored variously either black or white. We arbitrarily identify
one square as the "ant". The ant can travel in any of the four cardinal directions at
each step it takes. The "ant" moves according to the rules below:

1. At a white square, turn 90 right, flip the color of the square, move forward one unit
2. At a black square, turn 90 left, flip the color of the square, move forward one unit
