A couple of people have indicated that I should explain what poi are. Sorry about the lack of context. For info about poi (and how Hidden City and martial arts led to my being interested in trying them), see my entry "Swing time" from April 2004.
You can also see all the entries I've labeled as being in my Object Manipulation category, which encompasses juggling and poi, and would include other stuff (cup stacking, card tricks, cigar boxes, contact juggling, etc) if I ever wrote about such things.
(I apparently never linked to the cup-stacking videos I found a while back. Some day.)
