Juggling software I hear you cry? Yup, if you didn't know that it existed before, you sure do now!

Juggle Master Java
One of our favourites due to its simplicity. Also it see Ben Beever's most excellent book on siteswaps.

You have got to love this most excellent juggle passing 3D simulator; juggle chainsaws and why not - it's free!

Another juggle passing 3D simulator.

A decent DOS-based program, although the shareware version doesn't allow any more than 5 balls.
