I've had the United devices platform since 2005 and it's been working exactly as I wanted it to, i.e. a screen saver with a moving graphic to avoid burn in.
I've recently changed to the BOINC agent. So for I've only seen the screen saver for the project "Nutritious Rice for the World", (ironically the only one I opted not to participate in). In the background there is a photo of some rice paddies, above this photos I can see a model of a molecule slowly turning and in the bottom of the screen there are two bars showing the progress and the logos of WCG and University of Washington. Since I'm still using an old monitor I'm starting to worry about burn-in of the "permanent", non-moving parts of the screen saver.

1) Are the screen savers of all the WCG projects in the BOINC platform modeled in this fashion?

2) Is there some way to change this and make it like the United Devices screen saver?

If I've understood the threads I've read correctly I could turn of the WCG screen saver and use one of Windows' own but I kind of like being able to follow the progress without having to risk burn-in in the monitor.
