Get ready to lose yourself in videogames - literally. In May, the Excalibur Hotel and Casino in Las Vegas installed the first public Virtusphere, a human-sized hamster ball that lets you move through virtual worlds by walking, running, or crawling inside it. Until now, the sphere has been used primarily for military and police training.
Now, wearing a virtual-reality visor, anyone inside can play a first-person-shooter game or tour historic Russian architecture.
