Impossible Siteswap Animator 2.0
This is a juggling simulator that animates siteswap patterns, whether they're physically possible to juggle or not.
It can do siteswaps with negative numbers, like in this video: http://youtu.be/_5Q4UhyajC4
It can do infinite throws, crossing zeros, and invalid siteswaps.
It can also do patterns written in this version of mixed synch/asynch siteswap: http://web.archive.org/web/20110827122415/http://www.jugglingdb.com/compendium/geek/notation/siteswap/tweaked.html
