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.

Chlandi Figures

Visualizations of vibration patterns from 1787 by Ernst Chladni:

One of Chladni’s best-known achievements was inventing a technique to show the various modes of vibration of a rigid surface. First published in 1787 in his book Entdeckungen über die Theorie des Klanges, the technique consists of drawing a bow over a (circular, square, or rectangular) plate or membrane whose surface is lightly covered with sand. When stroked, a given plate will resonate at one of its natural frequencies. The sand bounces about on the plate until settling at nodal points (areas of zero movement) thereby producing intricate patterns. These patterns are now called Chladni figures.
