Vista DreamScene

Windows Dreamscene is an animated wallpaper and video technology for Microsoft Vista Ultimate, (note: It is ONLY for Ultimate). It is part of the Ultimate Extras package and runs on top of Aero Glass and apparently does not take up a lot of CPU usage. I have not tried it yet but the idea is very simply that you can use video as desktop backgrounds, be that some of the free samples that come with the package or use your own.
I intend to try it out soon, so will post some thoughts and findings then
