I am interested in science, so I am running SETI@home. This project is quite good, it gives everyone a chance to discover the aliens. I think there should be a cooler screensaver here.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
