JuggleMaster is basically a cross-platform Juggling animator [understands siteswap, for anyone who wants to know what it is]. Anyone who doesn't know what siteswap is can still download it and look at the patterns that come with it, and examine the cool stuff they could do if they did understand it.

Additional System Requirements:
