I had a productive evening yesterday playing around with Cellular Automata, in response to Stephen Wolfram's magnum opus A New Kind of Science . I put together a CA generator which calculates 90 generations of a 60-cell grid. That's 5400 cells. So when you click this here link , wait for a few seconds (around four on my monster PC) for the thing to finish crunching. It shouldn't crush your computer, although I have not looked at it on a Macintosh. The blank right half of the file is where the (self explanatory) controls will go in the next iteration of the thing. It still has a few bugs which won't be obvious unless you know what the thing is doing.
I will post the code when I am happy with it.
This evening I got all set up to start playing in Java. I will maybe have a more powerful version of the CA demo up in a couple of months.
