This ad apparently premiered in Europe a couple of days before my birthday, and the minute I saw it, I fell in love with it.
The love falls roughly into three parts: (a) The basic conceit of the ad. (b) The nuts and bolts of the production (i.e., working out how much of the construction really happened and how much only seems to). (c) Some of the little details (the [licorice?] windshield wipers and fan belt, the gelatin brakelights, the royal-icing detailing, the guy pouring golden syrup into a gingerbread crankcase…).
Altogether a yummy piece of work, and the ad agency should be proud of itself / themselves.
