A Mini billboard

The BBC has an article by Matthew Phenix about a billboard with a sense of humor:

Next to flashing Internet banners and late-night telemarketers, the roadside billboard may be the most maligned of advertising forms. The concept of the large-scale outdoor advert pre-dates the automobile by several decades, and it came under fire as a road-safety concern or as "visual pollution" almost from the start. And yet, despite generations of detractors, the humble billboard persists, and every once in a while, this low-tech medium gets a goose from some clever creative types. Such is the case with Google's recent foray into situationally aware electronic billboards, and so it is in Vienna, Austria, where the Austria-based ad agency Demner, Merlicek & Bergmann recently unveiled its cheeky Mini Stop Traffic campaign.
Fittingly playful, the scrolling billboards, which are moveable and have appeared at several high-traffic intersections in and around Vienna,  are synchronized with the adjacent stoplight, changing their color-keyed images time with the light. As the light turns red, a red Mini Cooper appears with the message, Es ist rot. Oder wie wir sagen: Blazing Red” (German for It is red. Or as we call it: Blazing Red). The ads, which earned the 2015 Epica Award award in the outdoor-advertising category, are just surprising enough to catch the eye, but not so clever as to bring traffic to a standstill.
