Airport clothing-store outlet United Arrows built a custom window display in its Tokyo location in which MarionetteBots (half mannequin, half robot) were wired with Kinect technology to mimic the movements of anyone facing them. The bots were all wearing United Arrows fashions, of course. On the one hand, big ups to anyone making creative use of puppets these days. On the other hand, the only thing more off-putting than a department store mannequin is one that dances joylessly for the public's amusement. At least these things had the good fortune to exist in a polite culture. In an American airport, they would have been touching themselves inappropriately and humping the windows within 10 minutes.
