T4K has never quite done it for me as T2k and TxK have and I think the main problem was after the immersion I got from TxK (by being so close to the screen) and Polybius (being in the screen) I just didn't get the same from a 50" TV from my sofa. (I had the same problem with TxK on the PS TV, it felt a whole different ball game).
So, as we're unlikely to ever see the VR T4K, I decided to try and do something about it.
I've just replaced my projector with an ultra-short throw one and when my son decided to opt out of movie night after I'd set it all up on Saturday I thought this was my chance. The short throw means you can get nice and close to the screen without getting in the way of the beam...
So T4K on a 10' screen standing about 4' away from it with your eyes pretty much in the middle of the screen. Lights off, sound up.

WOW!
I still suck compared to TxK (which I was only ok at), but what a way to play.
Next thing to do is dust off the Kinect and get out Rory McIlroy PGA Golf (as it has Kinect based golf swings) and try that on a massive screen...
