MarionetteBot at United Arrows in Japan is quite the window display. Mannequins + Kinects = window displays that mimic the motions of people passing by.
I don’t quite see the elegance or additional levels of Aha! in this installation, but if you look at the joy in the faces of the people passing by, I think you have to give credit to the fundamentally low-tech pleasure of puppets. The limits of these strung-up mannequins makes you want to push them farther. It summons more energy from the participant. Compare to any full-motion video interactive, especially those that are operated with buttons on a table.
