Here is something I picked up at Bob Sutor's blog. It is an article on g-Speak, a new Minority Report style gestural interface with recombinant networking from a company named Oblong. The presentation makes reference to a spatial operating environment. These ideas have been floating around the Internet for a long time now and seeing them implemented is exciting..
There is a video demonstrating the gestural i/o over recombinant networked resources.
Be sure to read article about the luminous room.
3D interfaces and real time continue their relentless if muted march into our lives.
