Two Dimensional Turing Machines
	Two dimensional Turing machine runs on an infinite square grid of cells. A good introduction and the current results of the 2D Busy Beavers you can find on Tim Hutton's page. Running a Turing machine on two dimensional grid gives you a good visual idea. With enough states and colors the possibilities are endless. The behavior of some machines is incredible. The result is so complex and unpredictable. Here are few example. All images on this page are created by 5 state Turing machines using 2 colors ( black and white ).
