3D Holographic Projectors and Screens

Here are 3 screens in development that are 3D holographic projectors or screens. One uses ultrasonic projection onto strong colloidal bubbles to produce images on the surface. Another from MIT uses modified high-speed LCD screens to create holographic images. The last one is a breakthrough from Japan for better holographic colours from all angles that could be used on screens. None of these require glasses.
