Star Trek-style holodeck becomes reality as scientists invent 3D virtual reality system (VIDEO)

Scientists in the United States have turned science fiction into reality with a wrap-around virtual reality screen where researchers can visualise their data in three dimensions.

Computer scientists at the University of Illinois at Chicago have created a real-life holodeck where astronomers can fly over the surface of Mars, and where "Star Trek" fans can walk around a life-size recreation of the Starship Enterprise.

Called CAVE2, it features screens eight feet high wrapped 320 degrees around the viewer.
