TetraBin
Take a look around nearly any populated area, and it becomes clear that getting people to dispose of trash properly is harder than it sounds. The TetraBin aims to make throwing away your rubbish fun by turning it into a game. A series of sensors inside the bin measure the size and shape of your litter, then trigger the release of a block inside the Tetris-like game shown on the outside of the can via a LED screen. As a result, people are encouraged to throw their trash away, the streets stay cleaner, and the trash bin becomes a meeting place instead of a foul-smelling obstacle.
