This page consists of two parts. The first is an example of the idea of Cellular Automata that Stephen Wolfram has made popular. It uses AJAX to fetch the drawing and formula without a postback. SQL is also used to fetch faves. The graphic is drawn from left to right one vertical line at a time. Whether a pixel is black or white is determined by the pattern in the three textboxes below. If the pattern matches that on the previous line drawn, a black pixel is drawn. The second is explained in its own popup.
