Lokitoth writes: Burton demonstrated a technology to draw animated 3D images in space, rather than on a 2D screen, by exciting oxygen and nitrogen in the air to give off light. The developers say: "This system can create about 50,000 dots per second, and its frame rate is currently about 10-15 fps. But we're working to improve the frame rate to 24-30 fps." Maybe the Japanese proposal to project 3D players to soccer fields world-wide is not so far-fetched.
