So I just had this weird idea that I'd like to share with you guys.
It's a tv that 3 (or any number for that mater-discussed later) people could use and all watch different things on.
You could sit there and play your Ps3 while your sister watches Twilight and your Dad watches the news, all on the same tv without interrupting each other.

Normal tvs run at around 30 fps or something like that. The way this would work is that the tv would run at 90 fps (for triple viewing capability) and cycle one frame of each different show or tv input in the time a normal tv would just show one. So now your tv is showing 90 frames per second and three different shows all modulated together. There needs to be a way to only view your frames though.

So you get to wear glasses.
They'd be set to block and unblock your vision at 30 fps (or whatever the tv is set to) coinciding each flash of vision with when your frame is shown on the tv.
As for sound, each pair of glasses has headphones that pick up the audio from your selected tv input.

What do you think? I'm keen to hear of any flaws or anything too if anyone here is into physics and stuff. (Or anything practical that I've missed)

tl;dr A tv that three people can watch three different things on at the same time without disruption. Now that you're curious, go to the top and start reading.
