I really like the look of the famous album art for Unknown Pleasures [1]. It was originally created by Harold Craft at the Arecibo Observatory from the signals of the first discovered radio pulsar [2].I made a spectrogram that produces a similar look. It runs FFT in Rust and visualizes it with WebGL.
