Paul Slocum has posted some info on his blog about his recent art installation- Televisions hooked up to Atari 2600's running custom carts, reflecting color combinations off a gallery wall:
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.
This piece will be installed at the McKinney Avenue Contemporary in Dallas, June 25th - July 30th.
