Press space for the next iteration! Hold space to let it run continuously! I made this by accident. Use turbo mode for it to run slightly faster.
This is an example of a Turmite (Turing machine termite). A Turing machine is a conceptual device that runs along a strip of code and edits it. The device runs on a set of instructions which are: Change the current square (code) to this colour (1or 0), move in this direction (left or right) and swap to this stage/state. Each stage has a different set of instructions, and the machine will also perform different instructions whether it is on a 0 or a 1. A "Turmite" is exactly the same, but works on a 2D surface.
