My goal with it was to test a theory -- an algorithm really. It can be found on the site at the 'Fields' page. It extends beyond cells. Take a marching band, for instance... You have 500 marchers, all blindfolded, and the goal is to get them to spill out onto the football field and form an intricate design. The constraint is that you have to give each marcher the SAME rules... that is, each marcher starts out identically to every other marcher. Well, the 'Field' algorithm is one way of accomplishing this. I made the program to see if the algorithm really worked. Like most things, it seems obvious in retrospect. But, before the program was done, it was difficult for me to really convince myself that the idea had merit.
