I work in Birmingham in the UK, Where I have been running SETI Screensavers to test the servers I set up for the last couple of years.
Thoughts about SETI and SETI@home
When I first came across Seti At Home I thought it was a massive millennium hoax. The screensaver ran a processor loop (tying up the computers resources) and occasionally updated a counter. It did this with wizzy graphics that looked cool and a little Star Trek NG scientific. At the stroke of midnight on December 31st 1999 up would pop a picture of ET waving happy new year!
It was not to be..
Have you considered what would happen if your computer was the one to analyse something significant? How long would it be before it was impounded by a covert government agency?
