From Chicago Business comes word of a new McDonald's billboard outfitted with aluminum arches that serve as a sundial. Designed to promote McD's breakfast offerings, the arches cast their shadow on a different breakfast item throughout the morning, until noon when their shade falls on a Big Mac. The billboard is the work of Chicago-based ad agency Leo Burnett. Located west of Wrigley Field, the billboard will stay in place until August, when the sun's light begins to change, designers said.
