Rovio Entertainment is counting down to the official 10th anniversary of Angry Birds on December 11, 2019, and their latest campaign aims to show how anger can be converted into positive action. Introducing the Angry Birds Venting Machine. Simply put, it accepts anger as its payment method, and offers special prizes for anyone willing to give it a good hit, shake or even shout. You’ll be able to find it in New York City’s Times Square for one day only (northwest corner, 45th St. & Broadway) on November 21, between 12pm-8pm ET.
