Folding@home is yet another distributed computing project, brought to you by Stanford. Basically, they're gathering computers to simulate protein folding, and hopefully solve that great, great mystery of molecular biophysics. Currently, the client software consists of a screensaver for Windows and console versions for Windows, Linux (only Intel at this time), and Solaris (Sparc).

The folding@home web site (http://foldingathome.stanford.edu) has tons of information on protein folding, proteins in general, and the mathematics behind the client. Perhaps the best part about the project is that for every sequence that is completed, an mpeg-format video and accompanying image files are released on the site. Also, since Stanford is a place of learning, the results will be shared with the scientific community. Most excellent.
