Ben Laposky was a mathematician and artist from Cherokee, Iowa. When he died in 2000, the art world lost one of its earliest computer art innovators. In 1950, he created the first graphic images generated by an electronic (analog) machine.
His electronic oscilloscope imagery was produced by manipulated electronic beams displayed
across the fluorescent face of an oscilloscope's cathode-ray tube and then recorded onto high-speed film. He called his oscillographic artworks 'oscillons' and 'electronic abstractions'. The mathematical curves that were created by this method were similar to the lissajous wave form.
