The “iBar” (guys.. really? iBar?) has a translucent top with projectors installed inside. It can detect objects on the surface and projects graphics linking them together… You really have to check out the video to see it in action. I’d love to know exactly how they are doing the surface detection. I couldn’t help but think of my own project (video) from my freshman Industrial Design studio last semester… and how I wish I had this level of sophistication in it.
At any rate, check out the link for a video and pictures.
