Holy. Crap. We see a lot of cool stuff around the 'net, but this is by far one of the coolest: MIT has invented a display-like gadget that sits on your desk and renders 3D content based on wireframe models beamed to it from Kinect. It lets you touch things without really being there, and it's a must-see.
It's called a Dynamic Shape Display, and it's designed to render 3D content without the user actually being there. It helps others interact with digital information in a physical way.
Voxels extend up vertically from the inFORM as required, and can take almost any shape. Got a bar graph you want projected into the real world? Awesome. How about interacting with a ball from a distance using a wireframe model of your hand rendered from a Kinect sensor? You got it. What about developing a design model and being able to collaborate in 3D with someone on the other side of the planet? It's easy.
The logical endpoint of something like this is when it becomes commercialised and sports a higher resolution. That way, we'll have little nano-rods projecting really beautiful, high-resolution models onto all sorts of things like desks, tablets, smartphones through to billboards and home appliances.
