Take a look at this “reactive wall” in Montreal in front of La Vitrine. It was created by Moment Factory and Photonic Dreams. Created in August 2009 it was originally intended to be a temporary installation, it’s since been made a permanent part of the club’s facade.
Sensors (it looks like they’re in an overhang above) track where people are, and in what direction they’re moving. Graphics react to their movements. I particularly like it when someone goes in the door — they have a sequence where the door lights up, and another where it’s like there is a spotlight is focusing on you.
It appears to be fairly simple — but fun. The graphics are basic, the color palette pretty narrow. A nice reminder that you can do entertaining stuff with very low-resolution displays.
