Linden Labs is celebrating the five year anniversary of the launch of their virtual world Second Life, and you're all invited, even if most of you won't come! In honor of this milestone, the Lindens will be holding a two-week long Virtual World Fair, complete with parties, roundtable discussions, and exhibits that highlight the genitalia perversion creativity of the world's residents.

Things kick off June 23rd with a keynote speech from Linden Founder and Chairman Philip Rosedale and newly appointed CEO Mark Kingdon, both of whom better have some pretty kick-ass avatars. If they don't have at least jet packs and glowing eyes I'm laughing them off the stage. Cue my character's temporary ban in 3...2...1.
