i set up a team with folding@home.
it is a distributed computing thing to share the processing of protien folding for research. so basically your computer will do some work for these guys in its idle time.

easy to setup, just got to put your team number in:
50548 (its called "CLIFFHOME" at the moment but i was thinking about changing it to "seabreeze kiters" or something.
let me know what you think.
i have 4 of my computers running cos i never turn them off anyway.
