Ben F. Laposky - Oscillons (1952-56)

"Computer art is often considered to have begun with Laposky’s oscilloscope images. A mathematician and artist, in 1950 Laposky became the first person to use an analogue computer to create graphic images, though he had previously experimented with mathematically-based systems.

To create Oscillation #4, he sent beams across the fluorescent face of a cathode-tube oscilloscope (or oscillograph), a device used to measure and graph the fluctuations in electric current. The voltage moves the beam up and down, tracing the image of the current on a screen.

Laposky recorded the mathematical curves and waveforms of the manipulated light beams onto high-speed film, producing artworks he called Electronic Abstractions or Oscillons.
