How do you hide a car?

Now isn't this interesting.

Mercedes, to promote their new fuel cell car, which they say is invisible to the environment, decided to run a marketing campaign where the car becomes invisible.

It's called computer-aided adaptive camouflage, where a camera on one side of the vehicle transmits an image to a display (in this case a mat of LEDs) on the other side.

From a distance, the car actually does seem to disappear, or at least blend in well enough to be hard to pick out.

But that only works if you look at it straight on. If you're to the side, the illusion is shattered. But that's one of the problems of this type of camouflage. But it's a start. And I'm sure there's someone working on a Harry Potter-style invisibility cloak ...
