I have a pair of older TVs that contain data readouts. However, because the screens don't always update they are susceptible to screen burns. I'm looking for a screensaver or something that could move around on the screen but not completely make the data disappear. The current running thing we have are the Windows Bubbles screensaver. This allows us to still see the data but it freezes the screens. (No data update)

I need something that will save the screen but still allow the browsers to do their screen updates as usual.
