you have to admit
ok, I know it is McD's but you have to admit this is a pretty cool concept in organic marketing... Engineer Leo Burnett has worked with the evilly massive corporation to create a unique billboard that will be on display in Chicago's Wrigleyville area (actually at Clark and Addison).
The board is based on a sundial and the M will travel slowly across the board throughout the day suggesting a different item for you to purchase, in relation to the time of day.
I hate to admit it, but I like it. More at http://chicagobusiness.com/cgi-bin/news.pl?id=21278&bt=burnett&arc=n&searchType=all
