This Jell-O Pudding Face interactive billboard on the corner of Grand and West Broadway in New York City is an outdoor ad that reflects the overall current sentiments on Twitter. The Pudding Face meter measures the smile and frown emoticons on Twitter, displaying the proportion of relative happiness to sadness beneath a man's face.
What's particularly clever about the Jell-O Pudding Face interactive billboard is that when the percentage of happy users on Twitter goes below 50 percent, Jell-O doles out coupons to passersby who look glum. See a video of the billboard in action below:
