Here's a wildfire simulator, that uses standard models for how fires spread through a landscape, using cellular automata: http://wildfire.concord.org/ http://wildfire.concord.org/ (It's designed to be embedded in a curriculum, so it doesn't have a lot of explanatory text, but it's pretty straightforward. Click the Spark button and add a spark to the landscape, and hit Play to start. For more fun, press the Terrain button and add a strong wind.)
