A new browser tool called Musical Spirograph turns childhood doodles into generative music with hypnotic precision.
The app draws geometric patterns—hypotrochoids and epitrochoids—using points that trigger notes as they pass through concentric rings. Users can adjust rotors, arms, scales, and synth presets, or even expand the range to two octaves. While the sound engine occasionally clips and lacks MIDI export, the experience remains engaging for casual play.
Built by a longtime tech journalist, the tool merges nostalgia with experimentation, offering six synth options and customizable parameters for real-time tweaking.
