Every weekend should involve a quick game of wall climbing Pong. That is, a game of Pong that is projected onto a rock climbing wall that tracks your body parts as paddles so that the ball reacts appropriately to each hit. It looks fun because you're actively manoeuvring your body around to smack that ball of light, but also looks so silly because you're hanging off a freaking wall and could, like, fall off at any time. The game is just one set up of the Augmented Climbing Wall. There's a lot more games you can play while trying to scale the thing.
