Pick from dozens of 3D scenes (geometric grids, particle fields, waveforms,
spherical patterns, shader-driven effects), tweak hundreds of controls in
real time, save and share presets, and smoothly morph between presets with
animated transitions. Add post-processing effects like kaleidoscope and
bloom, control the camera, and pick a background style. Audio is analyzed
entirely in your browser — nothing is uploaded, no account is necessary.
