Dear 100 Hour Board,
I realize this is a little late, but a while ago there was a discussion about where to get cool desktops or wallpaper or whatever you call it. I use "Astronomy Picture of the Day" at http://antwrp.gsfc.nasa.gov/apod/astropix.html, and I don't *think* it was mentioned. They have some really cool pictures in their archives, too, if you don't like the one for the day you go there. I recommend "Saturn: Lord of the Rings" and "Pleiades Star Cluster."
