SL’s Solaris II island is hosting Wishfest, which needs a bit of explaining:

A while back, things called “flash mobs” were all the rage in the offline world. Friends would text message friends, who would all meet at a certain place at a preordained time. What happened at that place was spontaneous, sometimes outrageous, and sometimes extreme. Nudity, pillow fights, and zombie walks have all been known to take place.

Solaris II has taken this idea into the virtual space, arranging what it loosely calls “Flash Festival.” The idea is that someone streams audio and/or video through SL, a notice is sent out to their friends, and people are free to join in and leave as they like.

The thinkers over at Wishfarmers are behind Wishfest, and it is an ongoing event, so get going and create your own
