I'm a computer geek living in Davidson, NC. I just did a major upgrade on my workstation, so I'm donating the extra CPU cycles to SETI@home. This has to be the coolest use yet for distributed data crunching.
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.
