So g.tec, the company that makes them, has come up with the following creative marketing strategy: Convince us that we’ll soon be interacting with computers through thought alone.

Here, for example, is a university project in which a student uses his brain to control a Rube-Goldbergian sort of etch-a-sketch, allowing him to write—albeit very crudely and slowly—without picking up a pen. And today at tech fair CeBIT, the company unveiled a new application that allows people, able-bodied and not, to paint pictures without lifting a finger.

The interface requires that you wear a skull cap studded with electrodes, but that won’t seem so awkward once we’ve all accepted that wearing cameras on our faces—aka Google Glass—is completely normal.
