I purposely don't take part in these threads because my pc displays on 7 monitors (5 17" tfts @ 1280x1024 and 2 21" widescreen tfts at 1680x1050) essentially a matrox G220 millennium and a matrox parhellia. Essentially though I have the same backdrop on all screens, and thats a simple blue comapny logo, uninteresting to you guys unless I were to blatantly advertise...
I am a firm believer of keeping your desktop as clear as possible though and only have a link to the recycle bin and a folder I call "current" for random files I am eorking on and not finished.....
