Using Your Wallpaper For Wallpaper

If your looking for some real cool wallpaper for your computer's desktop, then why not use a high quality digital picture of the wall behind your computer to give the illusion of the monitor being invisible.

I stumbled across this on BoingBoing.net this morning, the picture above was posted by Cory Doctorow and is accompanied by the following explanation - "Transparent Screens is a Flickr photoset of laptops whose desktop wallpaper has been set to a digital photo of the walls and windows behind them, so that they appear to have totally transparent displays. The effect is striking."
I thought it was cool too, for more invisible desktops you can check out a full gallery here.
