Well done and keep up the great work!
It's amazing how many different ways there are for an average person to contibute to scientific knowledge by using their computer to do number crunching.
I found out about a ste called Einsein@home here at FreeRepublic last year, and have been looking for Pulsars ever since whenever my computer is idle (63,894.23 Units done to date, and counting)

Another is the Stardust Project that is looking for cometary particles from the returned Stardust mission. My ranking over there is 880 out of 20,384 people who are also looking for particle tracks; not bragging as much as demonstrating how many people are involved in the Program.

All of these sites are tremendously fascinating, and deeply satisfying to participate in. Pick just one, and go have a blast with it...
There are a few more FReeper teams going at it on different projects.
If you are going to run a screen saver, change over to one of these distributed projects and make a difference!
