Description
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.[1]: https://en.wikipedia.org/wiki/File:UnknownPleasuresVinyl.jpg[2]: https://en.wikipedia.org/wiki/PSR_B1919%2B21
