Wii Zapper mod is virtual reality bliss

The tech in this video involves putting a laser projector and a gyrometer on a Wii Zapper. The video is extremely dark but what you'll see is how he can point around the room and the image will change depending on where he is aiming. Seems very impressive but I'm not sure how this could be harnessed into a consumers living room. I guess that's why they don't pay me to invent the hardware! If arcades were still big I could see a spherical machine made up for this so you can step inside and aim all around, blasting everything.
