3DTV stories

I think it's a safe assumption that 3D TVs that require viewers to wear 3D glasses aren't going to be around for too long. People don't want to spend $150 a pop on the things, and they just hurt the overall viewing experience. Luckily, people are hard at work on glasses-free TV, and we're starting to see some sets that offer up 3D viewing with no glasses required.
Usually, making 2D things into 3D things involves tricking the eye using special glasses, which make you perceive something has depth when it really doesn't. Surprisingly, the next advance in 3D could come by way of a gadget first invented in 1907, one that goes straight for your brain instead.
