Yeah, it's just a wallpaper. I use to have WIndowBlinds installed, but different skins caused some wierd effects to happen and using Remote Assistance made it worse. My computer would start running really, really slow. So I just got rid of it and just started applying different backgrounds instead.
At Wincustomize.com, they have you registering at their site after so many downloads right? I can't download anymore until I do. They got this cool screensaver that shows the galaxy in the background and planets coming in bouncing slowly in various locations of the screen. It also has a nice piece of music in the background. Cool.
