Space wallpaper (www.spacewallpapers.net) offers lots of free images that you can use for your computer’s desktop background (i.e. wallpaper), all of them with a space theme, of course. I love that stuff. The space wallpapers are created from NASA, ESA and NOAO/AURA images as well as from contributions from astro-photographers and space artists around the world. And yes Greg, nudewallpapers.net does exist.
The Old Negro Space Program is a 10-minute mockumentary about black astronauts in the 50s and 60s. I laughed all the way through it. (I found it through the J-Walk Blog this morning just before it went down.)
