Editorial interest 84/100 Selection signal · not a rating of the site

A browser-based visual instrument that folds 3D fractal space to live audio and lets you explore the result in an apparently bottomless dive.

Landing page captured for the 2026-09-06 issue.

Field notes

The instrument accepts a file, microphone input, or radio stream, then routes seven frequency bands into fractal geometry and lighting. The page lists eleven fractal engines—including Mandelbulb, Mandelbox, Kleinian, and Menger—plus twenty-four palettes and eight reactive lights. It also describes HQ video export at the exact frame rate with accompanying audio. MIDI and direct DAW control are labeled as forthcoming, while the Dives section currently contains no published examples.
