To promote its new B-Class car, Mercedes made it "invisible." Essentially, they draped one side of it in a fabric of LEDs that displayed an image of the scene behind the car, creating the illusion of invisibility. (This approach is similar to the active camouflage prototypes demonstrated by the University of Tokyo and elsewhere.) While a startling demo, it's not very practical — it required 1,100 pounds of gear inside and $263,000 worth of LEDs.
