Swivl Turns Your iPhone Into a Self-Tracking Cameraman

Swivl is a new $139 accessory that lets your iPhone camera automatically track your subjects as they move around. GigaOm explains its possible uses as "Folks could have hands-free FaceTime chats on an iPhone or iPod touch, for example. Educators could easily record their lectures and be able to move around the room. And I’ve been meaning to analyze my terrible golf swing with an iPhone camera; I could do that and not worry about having to stand still in one spot."
