Chemicalburn: a transportation network-simulating screensaver

So this past weekend I realized that I still had the great Skyrocket screensaver on my Powerbook from the Fourth of July-- no, not this year's. Last year's. It was time to get a new screensaver.

Fortunately, FreeMacWare was featuring Chemicalburn, a screensaver by Michael Ash (who also created GPULife, a Game of Life screensaver) that not only looks cool, but actually simulates a transportation network. Nodes get created randomly, and little colored packages fly around between them, as frequently used routes get stronger and stronger. When a route is destroyed, the network eventually fixes itself, by creating more routes and nodes. Not only is it aesthetically cool, but it's a great thought experiment, and it's fun to watch a little network get created and destroyed when your own work goes idle for a bit.

Chemicalburn is open source and free. You can get it on Ash's website.
