Ah yes, a great video indeed. I should have thought to recommend it when you mentioned taking up juggling. There is also a video of a man doing this same exact routine with twice as many balls (look up "Chris Bliss dis" on Youtube)-- but despite the fact that it must require amazing technical skill, I still think the original works better as performance art.

I'll have to remember to ask my brother for more recommendations of juggling stuff, as he is very into juggling and other circus arts. I should get him to post one of his routines somewhere!
