Two students, Sandro Engel and Holger Michel from the HAWK University in Germany, worked on a awesome project. They created a ping pong game near a crosswalk. The crosswalk controller turns into a ping pong game once the lights turned red. Your opponent isn’t a computer but somebody who is waiting on the other side of the crosswalk, which makes it a new kind of social media. Too bad the system isn’t real though. They used visual effects to create the video, however we do like the idea a lot. Who knows, maybe in time somebody will ask them to implement their idea.
