Let's face it, 3D movies are amazing but there are times when you'll walk away with a killer headache. A group of researchers at IMEC believes that holographic video might be the best way around this problem and has been working on a means of constructing holographic displays by shining lasers on microelectromechanical systems (MEMS) platforms capable of moving up and down like small, reflective pistons. Here's the cool part: each pixel would have a spring-like mechanism attached to it that could be moved by applying voltage to it.
