Mercedes Cloaking Device

It's not often that folks want to hide the fact that they're driving a Mercedes, what with plenty of them being among of the finest motorcars on the road. However, as part of a marketing plan to call attention to its zero-emissions F-Cell model, the German marque swathed a side of one in LEDs to give it the ultimate in camouflage.

You see, in addition to that makeshift display, a Canon 5D Mark II was mounted on the other side of the car so that video of its surroundings could be shown on the LED bodywork -- rendering the car all but invisible to onlookers, as long as they're staring at the left side, of course.
