Few things are more luxurious than an indoor rock-climbing wall. But even those lucky enough to have them, must contend with the hulking structures. No one has re-considered the design. That is, until it was transformed from the standard pebble-like holds into a wall art comprised of indented ripples. When not in use, it?s a backlit piece of sculpture. But when you?re ready for some bouldering, a clever UI idea kicks in: A companion iPhone app lights up a route according to your preferred difficulty and then rates your performance. Very cool.
