what you after is a lot easier than gradient (I should know after writing it myself, well 90% anyway).  If you want some help with writing it into a script just add me to wlm and I'll give you a hand.  I recomend you have a look here for understanding how to do commands and here for saving this into the registry.

I didn't really want to do it for you because it is a nice simple-ish script to start with and it always feels good when you write a script.
