Langton's ant with MatrixCanvas

A universal Turing machine with only two rules:

At a inactive tile, turn 90° clockwise, flip the color of the tile, move forward one unit.
At a active tile, turn 90° counter-clockwise, flip the color of the tile, move forward one unit.

An ant starting on a blank canvas would move on infinitely. (It does stop at the edges of the canvas in this implementation.)
