The print on this McDonald's billboard is nothing to write home about. But the addition of a sundial mounted on top turns it an innovative and brilliant piece of design. Displayed is the fast food giant's breakfast menu, with the sun casting shadow on each item that corresponds to the time of day you would normally eat it.

Created by ad agency Leo Burnett, the sundial not only points out what meal you should go for, it also creates a shadow of the restaurant's infamous 'M' as it does so.
