Phosphorescent sticks bending through geometric space.

Glowsticks v2 02 is built around the visual metaphor of luminous sticks swept through darkness — except the sticks are rays traced through a high-pass-filtered geometric field designed by Geiss. The light trails respond to treble content specifically, making them ideal for tracks with complex high-frequency movement.

Geometry Lab

Cleaner lines, surface work, and deliberate patterning. These are the presets that feel architectural rather than painterly.

Glowsticks, oscilloscopes, prisms, cubes, and hard edges.

How it works

Audio-reactive shaders, running entirely in your browser.

Upload any audio

Drag in a local file, connect a mic, stream a radio URL, or use one of the included sample tracks.

Real-time analysis

The Web Audio API analyses frequency content, amplitude, and transients at up to 60 fps, all without leaving your tab.

Shader renders the result

Butterchurn translates that data into GLSL shader parameters. _Eo.S. - glowsticks v2 02 - Geiss HPF maps those parameters into its own visual language.

No account. No install. Works in any modern browser with WebGL2 support.
