You may not like Bruce Banner when he's angry, but you'll undoubtedly love this BMW X6 when it gets wet.
It's the work of German graffiti artist Rene Turrek, who used a blue paint that becomes transparent when exposed to hot water, revealing the (very angry) Incredible Hulk beneath. Think of it as a life-size Hot Wheels Color Shifter.
Turrek shows off some process photos on his Facebook page. Watch the demonstration video below.
