I've recently purchased another monitor, my first one being a TV and being much larger. I now sit at a desk and use my shiny new 24" LED more often, but I like to extend the desktop into the TV. The problem presented with this is to save power and the longevity of my 47" VIZIO, I try to keep it off when possible.

What I'm seeking sounds very simple - If any of you have ever used Compiz or Deskspace (Yod'm) - You'll know what im referring to when I talk about a "cube."

The most important functionality I'm looking for is the ability to scroll desktop contents between both displays and virtual desktops.

Deskspace does and excellent job of presenting an attractive cube, but it creates a separate cube and virtual desktop space for the second extended monitor (now the TV) - Again, what I'm looking to do is scroll between virtual desktops, by passing through both monitors. The net effect of this functionality would allow me to scroll the contents of the extended monitor to the first monitor should a window get caught there without having to turn on the TV.

So imagine the horizontal portion of a cube as being actual real monitors - is there anything that allows one to rotate desktops between displays?
