Waiting for stuff sucks. That’s why God invented smartphones—so we’d have something to do while waiting for elevators and crosswalk lights. Although the downside to playing with your phone while waiting is that you can easily miss the thing you were waiting for. To solve that problem some clever guys in Germany have come up with an interactive traffic light concept. The button for the light features a screen that allows you to play pong with a person across street while you’re waiting for the light to change. Unlike playing on your smartphone, it alerts you when the light has changed so you don’t miss your chance to cross the street safely.
