In collaboration with Keep Adding, I animated a 3 channel syncronized HD loop of a 40 minute background animation for the main wall of the restaurant.  The playback was done on 3 networked mac minis running a custom quicktime based playback engine to allow for perfectly syncronized playback as well as automatically managed boot and shutdown times.  The guys at Keep Adding did the core of the design and the physical install and I created the playback system and the animation.
This is a condensed 1 minute version of the 40 minute 3 channel HD video loop.  In the actual installation this is paced so that during the average dinner it cycles from day to night and rains once.
