This is my first image of the day. I just finished writing a screensaver for fun
using directdraw. It only uses directx for access to video card memory and the
surface flipping. The basic idea was to have a bunch of different particle
system effects that can be smoothly transitioned. It works sort of like a dj
spinning records. It plays one effect for awhile and then "crossfades" to
another. You can download the screensaver from www.dropdesigns.com/astral.
