Idryonis Studios & EnTCo have teamed up to create one
wild ride (just look at the thing!). They like to call their little invention Monster Roll Cage:
"...enables two riders to race and participate in a virtual off-road truck competition with a 48 inch high definition
projection screen and a 500-watt bass-blasting Dolby 5.1 surround sound system."
Apparently you can rent this contraption for parties… Let us know how it turns out!
