I just stumbled upon a demo of a product called BumpTop, which is a 3D workspace that replaces your standard Windows desktop. It works with either a mouse or a multi-touch screen — but it has some impressive innovations for interacting with data on a computer.

The demo reminded me of Tom Cruise in Minority Report — imagine this kind of technology spread throughout all of the applications we use.

We haven’t even begun to scratch the surface of what computers can do. The next generation of touch and voice input are going to be revolutionary.
