Kraft’s Jell-O Pudding brand is looking to turn your Twitter frowns upside down.

The brand this week unveiled the Jell-O Pudding Face Mood Meter, which detects smile and frown emoticons on Twitter. The website shows a guy who is either frowning or smiling based on the mood of the country.

On average, there are 800 frowns and 1,200 smiles a minute. When the mood deviates from that norm, Kraft sends recent frowners a redemption link for free Jell-O Pudding. When those consumers click the link, Kraft encourages them to use the :D "pudding face" emoticon. Those count as smiles, in theory bringing the total count up.

In addition, there's a Twitter feed for the campaign, @Jell-OMoodMeter, which so far has only 100 or so followers. But the brand hopes to spread the word by name-checking frowners in the feed and giving them pudding. For instance, Twitter user @jonheller used the frown symbol regarding Apple’s Lion OS X release. “What’d they do with spaces :(,” he asked, and got a callout from the Mood Meter: “Woah there, Leroy Frown. We saw that :( and we’re not happy about it. Have some FREE pudding.” A URL then leads to a site where he can get pudding if he verifies his identity.

The work is the latest attention-getting stunt from ad agency Crispin, Porter + Bogusky, which broke some innovative Twitter campaigns for Jell-O sister brand Kraft Macaroni & Cheese earlier this year and is now doing some interesting outdoor work for Vitaminwater.

This isn't the first attempt to gauge the country's mood via social media. Facebook examines the same issue in a less tongue-in-cheek manner with its USA Gross National Happiness Index.
