This is the Augmented Climbing Wall. It's a climbing wall that's been projection mapped and uses a camera to track climbers' movement. You can use it to project a route up the wall or play climbing games. In this case, Pong. You can buy one if you're interested, although I imagine they're expensive. Or you could build your own. Or you could go outside and climb a mountain. Or scale the side of this office building and kidnap me, I won't try to stop you. Just a heads up though: there isn't anybody on this planet who would pay a ransom. Other planets, yes, but it would take them years to show up with the money and I'm a very unruly prisoner.
Keep going for a video demonstration.
Thanks to Catman, who's probably only doing it to try to win the affection of Catwoman.
