Kind of a cool billboard for SunChips, part of a campaign written up by Stuart Elliott in The New York Times this morning. In New York, it probably took some time to find billboard locations that actually get a decent amount of direct sunlight every day. Not to mention, the ads might look a little odd at night and on cloudy days. Other billboards have made use of shadows, of course—notably, McDonald’s sundial and the World Wildlife Fund’s rising-oceans ad.
