OK, it's only 640x480x16, but it still looks cool.
I got the workbench backdrop from an animation somewhere, and the Window
backdrop came from the LCARS display at http://firstcontact.msn.com.
I modified both pictures using Deluxe Paint IV. My computer's an A1200 with
no graphics board, and only 2MB chip, which is why I don't have a monster
1280x1024x24bit screen.
If anyone's interested in the icons, let me know. If you want the pictures,
you should be able to delete alll the current icons in a picture editor.
