There are some settings in /home/root/Settings/qpe.conf that you can play around with.
You can specify an image using the key \"ScreensaverImage = \". Point it to a PNG file somewhere on your Z (full path, to be safe). QT seems to automatically display this image in a random position and it jumps around randomly at a random time interval. I don\'t know of any way to disable or control this. So best pick a somewhat small image that will look cool bouncing around your screen.
I used the Amiga ball!
