Nebula OpenGL screensaver

(Click here to enlarge)

Updated 3/11/01.  I improved the installation, and the visual quality is a little better.  It now has a preview box, and works like a normal screensaver.

This screen saver is very small and very fast.  However, the effect it produces is very cool looking.  It is the kind of screen saver that won't bog down your computer.  The theory behind it is this:  there are many particles flying around each other; each one exerts a force on every other one.  In the process of doing this they also leave a trail which brightens as other particles pass over it.  Your computer must handle 800x600 resolution, and your video card must support OpenGL. Other than that, the program should run smoothly on any machine Pentium or faster.


P300, 64MB, with a decent video card that supports OpenGL.
