Paint that changes color?

There used to be an early 90's Ford Probe in town that had that type of paint job on it. From what I've heard Ford had it as an option for those cars back then. I could be wrong just what I've been told. And it is apparently really hard to get done properly gotta get someone who knows what they're doin.

My opinoin is that it's neat to see but I would never get it done on a car that I own.
