Do you want your system to have six desktops? And each desktop has a different background and runs different programs. DESKSPACE is such an awesome software. It runs with very little memory, even with 512MB of memory it can still run. If you categorize your work, games, music, movies, chats, etc., on different desktops, and want to switch between them, just press win+1/2/3/4/5/6 (you can set it yourself) to switch desktops, and it switches dynamically in 3D, isn't that cool?
This is a fun software that I've personally tested. If any of you are interested, you can go download and try it out.
