Talk:Gravity globe

Precedents in other SF?
I'm absolutely certain that I saw something identical to the grav globe in something before Doctor Who--a self-powered anti-gravity room-filling flood light with the exact same name. But I can't think of where. And if I try to search, all I find is the Levitron Anti-Gravity Globe and 100 clones....

Anyone know? --Falcotron 03:02, April 27, 2010 (UTC)
