In Avatar, the star was in a wheelchair, but in his Avatar body he could walk. Would that be nice? For the moment the best we can get is what Darkworks is now producing. They will this year produce 3d games on consoles and regular 2d displays. They do this by post-processing the existing 3d data into 3d images. Special glasses then render the 3D data with true colors and sharp images. Unlike the red-and-blue anaglyph of the past. The images can also still be seen in 2D without glasses. Games can be enjoyed by everyone in the room with or without glasses seamlessly. How great is that? Well, not like in Avatar, but nice anyhow...
