Here’s a cute picture of me doing a break freeze "in Second Life" using a green screen and a digitally super-imposed backdrop.
Linden Lab set up a fun photo booth at the Second Life Community Convention where people could get their real live selves placed in a virtual background, from drinking in a pub to underwater to driving a racecar. I of course chose the nightclub background and did a quick freeze that had people applauding.
Good times.
