Juggle Saver

Juggle Saver is a freeware Windows screensaver that accurately displays juggling site-swaps in 3D. You don't need to understand what site swaps are to appreciate its hypnotic effect.

In summary Juggle Saver features:

Real time 3D mesmerizing graphics rendered using OpenGL (hardware accelerated if available). See below for an example screenshot. (Note that the animation of the actual program will be a lot smoother, I've reduced the number of frames in the animated GIF to keep the file size small)

Click image to start animation
Dynamic view position adjustment while screen saver is running (Win9x only) or being previewed (all platforms).
A range of juggling objects including: clubs, rings and balls.
Access to over 200 pre-defined patterns. The current list of patterns was compiled from various sources by Issaac Orr, check out his homepage for updates etc.
Completely free. Juggle Saver became completely free as of version 0.33 and no longer has any restricted features. If you have an older version and would like to access the registered features then see the registration page for a free keycode to use.
Tiny self extracting download: JSInst.exe (98K). For further details about installing the program see here.

Note for Linux users
