Oscilloscope Art Portraiture

Use an analog oscilloscope in X-Y mode to render vector portraits by feeding carefully shaped audio signals into both channels. Compose stereo audio waveforms in code or a DAW that, when routed to the scope inputs, draw recognizable faces or objects on the phosphor screen, then photograph the glowing traces as finished art pieces.

Oscilloscope Art Portraiture

The face on the phosphor looks almost friendly. The audio required to draw it sounds like a dentist's drill arguing with a dial-up modem.
