Saturday, June 15th, the last day of the 2002 Usenix Annual Technical Conference, was also World Juggling Day! Hence, the jugglers came out to play in one of the plazas adjacent to the Monterey Conference Centre.

Not exactly what I consider juggling in the traditional sense, but this is a wheel being balanced on the string running between the two sticks. As the wheel spins, it creates a whistling sound. There's probably a proper name for this skill, though I have no idea what it is.
Ah, traditional juggling!
