Go to any arcade. Observe how every CRT in the place has "Insert £1 
Now!" faintly displayed in the center of the screen, regardless of the 
image from the video card...

The idea of a screen saver is that it displays different images so that 
no one particular area of the screen gets unduely stimulated. But lots 
of modern screen savers display static or nearly static images...
