A simple concept can certainly go a long way. In order to promote Mercedes new zero-emission technology, cars were covered with special LEDs that emitted video of its surroundings, causing them to blend in with the environment. The message is simple and clear: “0.0 emissions; that means it’s invisible to the environment.” This interactive idea has gotten over 8 million people already talking about the new technology. This is such an effective idea to get buzz for a brand and go viral.
