"United Visual Artists have created a new site specific work for the Oyane Plaza, in the Roppongi Hills district of Tokyo, to mark the opening of UK-Japan 2008. Contact is a responsive floor based installation which allows visitors to use their kinetic energy to generate audiovisual forms that will interact with the user, and communicate with each other. Contact marries advanced computer vision techniques, physics simulation and a unique display surface to create an experience that aims to highlight the results of peoples interactions with each other, and their environment."
Saw this installation piece in the video posted previously for openFrameworks (post). Shows brilliantly the sort of idea I imagine for the screen again, and also for the type geometric graphics I envision and used in examples for The Art of Ping Pong - some fantastic images below and video (its great shows how the interaction with the shapes work) on United Visual Artists site.
