Truchet Tiles
Because the ant turns 90 degrees each time it turns, you can divide up the
grid into horizontal and vertical columns. These columns are denoted by the
cell's Truchet tile. There are four tiles, two horizontal tiles (a left
orientation and a right orientation) and two vertical tiles (again in left
and right orientations). When the ant enters a cell its handedness is
flipped (if the cell had a left orientation it's changed to a right
orientation and vice versa).
Truchet tiles are used to prove theorems about the properties of the
ant. See the paper
"Further Travels with My Ant" by Gale et al.
for several applications of Truchet tiles to proofs of ant properties.
