I watched a really interesting doco that screened in the uk a couple of years back about John Logie Baird (the inventor of TV). The doco was called JLB - the man who saw the future. It was fascinating - I never realised that he had demo'd and was pushing for a 1000 line colour system shortly before his death in 1946 and also had working prototype 3d tv (that didnt need glasses).
Hmm - back to the future - its taken a while.
3d - not a gimmick once you dont need the glasses.
