The guy on the unicycle is Casper, a Los Angeles-based anon. Shortly after his triumph at Gold Base, he was protesting at the HGB in Hollywood when he was physically attacked by Sea Org member Gigi Scudarelli (who was put up to it by guard Andy Knapp).
Scio lawyer Rick Moxon recently attempted to force Casper into a deposition in a case he had nothing to do with (Moxon has a record of abusing legal process to pursue fishing expeditions for information). Casper ignored Moxon & the depo. The matter was dropped.
