These M&M ads have a great idea going for them, but horrible execution? All of the various candies make up an image, but it's almost impossible to see close up as a print ad. If you want to see them, enlarge to fit your screen and then step/roll/crawl back about 10 feet and it should become clear. Turn them into a billboard, and I'm hooked.
