Show HN: A spectrogram in the style of Unknown Pleasures album art (Rust+WebGL) 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://ift.tt/Eahfp50 [2]: https://ift.tt/dOk5Vjv https://aestuans.github.io/spectrogram/ January 5, 2026 at 05:34AM
