The problem with food ads is that you can only see the product, but you can’t smell or taste it. Until now, that is.

In Germany, a billboard for the GranataPet brand dog food lets consumers (or actually, their dogs) get a sample by checking in via Foursquare. As this video shows, once you check in, dog food comes out of a dispenser at dog level. As detailed, the checkins are noted on a distant server that is connected to a black box in the billboard that controls the dispenser.
