We don’t have real Transformers yet, but this might just be the next best thing. Rene Turrek, a German graffiti artist, decided recently to make a color-changing car with a little dash of Marvel Comics fandom thrown in. So, he took a BMW X6 coupe, painted cool images of The Hulk on it, then covered the whole thing in a heat-sensitive blue paint. So, when you throw hot water on the blue paint, the Hulk is magically unveiled beneath.

It’s a very fascinating thing to watch. The only problem is you have to bring your own hot water…unless it’s raining hot water…but if it’s raining hot water, that means Ming the Merciless is invading, and we won’t be worried too much about our cars.
