Major technical conferences are one of the few places where enough people with juggling skills can get together to make interesting passing patterns. Below are some of me and my friends at Apple's WWDC.

Above I'm at Moscone West for WWDC 2005. To the right I'm at Apple's headquarters.
Then some kind fellows shot movies of us.

You, in the meantime, can look at Renegade. That's where I ordered my six juggling pins for passing. Also, the Juggling Information Service is an interesting find.
