I first saw someone do this a few weeks ago, and it seems to have gotten fairly popular. The idea is to take a picture of the area that you keep your computer (without your computer in it), and then set that picture as your desktop picture, or wallpaper for you PC people. You can achieve a sort of invisible desktop.
I found this image on the site of Matt Jones. I think he did an excellent job. I haven’t tried this yet myself, but I imagine that it takes a few tries, and is a lot easier with a laptop.
Give it a try and see what happens.
