Interesting that this is out of the MIT Media Lab, since the Minority Report interfaces were based on earlier work there by another guy, who has since spun it into the spatial operating environment g-speak (oblong.com).

That said, I'm super into the fact that the extension is open source and the technology is available for others to build spatially-aware interfaces. Really, really cool work that I know I'll want to check out further.
