There I was, just the other day, going on and on about ambient media and what should I see just now but this new execution for McDonald’s from Cossette West. A truly inspiring piece of genius that must have cost an absolute fortune…but for work this good, money shouldn’t matter…

The brief was simple: Get the message out that McDonald’s is now running a free coffee promotion. So how did they go about it? Why…by transforming a common streetlight into a giant carafe pouring coffee into a massive McDonald’s coffee cup.

Pure genius.
