My desire to take public transportation would grow exponentially if every subway and bus was equipped with a Game Strap. The Game Strap is a redesign of the handheld strap commonly seen on buses and subway cars. The strap can play one of five games and was designed by Jian Qiang.
The Game Strap is activated when gripped and features only a directional pad as its controls. The strap informs gamers when they're nearing the next station to ensure that serious gamers don't miss their stop. Luckily the strap's games aren't that complex, with names like 'Shooting Game' and 'Water Game' indicating their lack of complexity. 'Tetris' is a nice addition however, and I could see it easily being the game most played.
The Game Strap Turns Boring Subway Rides into High-Scoring Quests
