I run a program on my computer that analyses data gathered from the Search For Extra Terestrial Intelligence project or SETI@home
I wondered if anyone else was interested in this kind of thing so here is the link to the site.
It's easy to do and certainly the seti screensaver looks pretty cool.
There are other projects you can sign up to process too but I dont have any experience of those.
http://setiathome.berkeley.edu/You download a thing called BOINC then add SETI or which ever one takes your fancy and away it goes then when it's done it downloads a bit more information and processes that.
Easy to do, and helpful to those who are looking.
