Join us tonight starting at 6:30 p.m. PST (9:30 p.m. on the East Coast) for opening remarks and a ribbon-cutting by editor in chief Mark Jannot (PS Mandelbrot in-world), and stay to check out live sets from PopSci podcaster Jonathan Coulton as well as Second Life musicians Nance Brody and DJ Nexeus Fatale. Or swing on up to our green-roof dancefloor/garden. Or pick up a shiny new Nokia 770 Internet Tablet for your avatar to chat with. Or kick back and see the video on our massive solar-powered flat screen. Or fly around on a kick-ass rocket-powered PopSci Slegeway (we're giving one free to the first 100 attendees. I've already logged some serious flight time, and they're a blast). Seriously, PopSci knows how to virtually throw down.
