An effective advert doesn't necessarily have to be a multi-million pound production. Remember that Nike ad with Tiger Woods bouncing a golf ball on his club? It was supposed to be completely different until the director saw his skills on set. VW had similar luck with this ad made with nothing but an action cam attached to the spinning wheel of a driving car.
The beautiful effect was simply the blurred results of a glowing city at night, accented with some freshly fallen snow. It's certainly not for those who get dizzy easily, but it's a memorable ad that probably cost the company the price of a GoPro camera and some post-production. [YouTube via Notcot]
