Whatever you decide to post on Twitter, the Tweet Sleeve will reveal your feelings to the physical world you're currently inhabiting. If the lights are green, the coast is clear and you're having a zip-a-de-doo-daa day. But look out when those blinkenlights turn red, because somebody is on the warpath.
This is one smart hoodie (almost a smart is that garment that taps you on the shoulder), scanning the text of your tweets and using some algorithmic gobbledygook to figure out whether you're happy or sad. For her next project, perhaps Tweet Sleeve's designer Vanessa Sorensen might want to bypass Twitter altogether, and jack the system directly into the brain.
