I found this on we make money not art today and thought it a fine piece of art.

Instead of presenting complex images (computer programs or photographs) each computer of The Analog Color Field Computer (ACFC) repurposes its monitor such that a solid field of color is spread across its entire display. And instead of producing complex sounds (clicks, beeps or music) each sculpture produces a pure musical tone.

By minimizing the content of its audio-visual renderings to solid colors and pure tones, the device offers relief from the myriad of visual, sonic and operational conventions traditionally associated with computer systems. The audience can adjust the hues, pitches and rhythms of each computer and thus assume a role previously reserved for a computer's video processor. They can manually regulate the electrical currents that command the monitor's color circuitry. The ACFC does not employ display systems as media for the visualization of computed images, instead the aesthetic artifact is derived from the physical manifestations and electrical workings of computer monitors themselves.

The piece also points to the rate at which Cathode Ray Tube based monitors are being discarded to leave the space to the much leaner flat panel displays. The ACFC gives the screens a new life as pieces of art. As a tribute to the CRT century-old technology, the installation utilizes analog electronics almost exclusively.
