Rovio is aiming to do something a bit different for the tenth anniversary of Angry Birds on December 11th. What started out as an addictive mobile iPhone game has morphed into a multimedia giant, spanning two films,virtual reality and tons of merchandise. Now, together with the creative firm Droga5 , the company wants to let let you express anger in real life with its "Venting Machine." It's exactly what it sounds like: a vending machine that you can punch, shake and shout at in the middle of Times Square's maelstrom of activity. Once you're done, you'll get a small prize that'll hopefully help you chill out a bit.
