The setup is 3 TVs facing the wall attached to 3 Atari 2600 consoles, and
the Ataris are programmed to play a repeating sequence of color that lasts about 4 minutes.
Each color is actually made up of two colors that are mixed by displaying one color at the top
half of the screen and the other one at the bottom, and the two are swapped at 30Hz. It gives the
sense that the colors are flowing. And the refresh frequency for each TV is gently modulated out of
sync with the others, which gives the light even more motion.
