I loaded the original screen saver on a cube farm of computers when it first came out. Wish I would have thought to have taken a picture of the cacophony of color that resulted when you turned the lights in that room out at night but had all the computer monitors on. Then again I might have not even owned a camera back then.

I haven't crunched SETI for years, but I do still tilt at numerical windmills - Primegrid can be great fun if you are lucky enough to hit a mega prime (I have three!).
