Someday, everyone will have a virtual reality cocoon

Nerds at Iwata-Yano Laboratory at Tsukuba University in Japan have created what they call the Media Vehicle. The contraption is a virtual reality "cocoon" where you can immerse yourself in a spherical display, surround sound and gentle G-forces courtesy of the computer-controlled wheels, which drag the whole thing this way and that to make you feel the motion. I want one.
