Holy Star Trek-Tech Batman! A creative developer team (called Artanim) created something they call Real Virtuality and it really takes VR tech to a whole new level. The folks behind the tech mixed an Oculus Rift with a host of external sensors & cameras, and even included some interactive objects to create a multi-person experience that is a big step closer to the HoloDeck as seen in the Star Trek Next Generation TV series.
While their developments obviously are not a true HoloDeck experience because they still require the user to wear body gear, it's still a remarkable achievement. Furthermore, it looks like this tech will actually be showing up in some theme parks within the next couple of years, so it is something we all might get to experience first hand.
Eventually, as the tech progresses, we might be able to have something like this in our homes too! Enjoy this Off Topic video in the thread below.
