I just came across this and it looks promising. I wonder if it will be available by the time BoB gets here. (Would be good with Track IR)
There's been some interesting technologies in the press over the last few years but not many of them are making it onto the shelves in any big ways.
Some of my favourites were the data contact lenses (as shown on Rabbits)
The Nvidia 3D glassess (Need 120Mhz monitor)
The big curved screen (not sure who by)
Cheers
