3. McDonald’s Sundial Billboard

Back in 2009, there is one certain McDonald’s Billboard, created by the Leo Burnett ad agency that gets the attention of most people in Chicago along the corners of Clark and Addison Street. What’s the hitch? If you observe the ad between 6am to 11am, you can see it point at products from coffee to a burger, and 12noon lets you see the “M”.
早在2009年，在美国芝加哥的Clark和Addison街头，就出现了一块由Leo Burnett广告代理商设计并制作的麦当劳广告牌，引起了不少人的关注。其中有什么小玄机吗？如果你在上午6点至11点看到这块广告牌的话，那么你会在上面看到从咖啡到汉堡包的各种麦当劳产品，到了中午12点，广告牌显示进入了M时间。
