What do you want for breakfast?

In 2006, McDonald´s set up a billboard that functioned as a sundial in Chicago. The aluminium set of McDonald´s arches (4x3,5feet) cast a shadow on a different breakfast item each hour until noon, when it cast a shadow on a sandwich, singaling lunchtime.

The advertising agency and an engineer had to do a lot of research to find the perfect location for this uncommon ad.

The billboard went up near the intersection of Clarck and Addison, Chicago.
