Dual Displays: Wallpaper 2 Randomising

[Sharp-kun]

I'm probably hoping for a bit much here, but here goes.

Using Nvidia's nview software I've got 2 screens. One is my main CRT that I use for everything like net browsing etc. Two is my TV, I really only stick videos on that. Each has a seperate wallpaper.

Is there any way to randomise the wallpaper on the TV while keeping the CRT's one the same?
