cope
A gentle ascent through layers of translucent atmosphere.
Soar v2.0 renders layered atmospheric hazes that shift in color temperature as the audio's energy changes. The motion is always upward, always gradual — even under fast music the ascent never accelerates beyond what feels graceful. Cope built it for long listening sessions: it never demands attention, but it always repays it.
The quieter side of the library. Scenic, spacious, and less demanding, with enough motion to stay alive without stealing the entire room.
Softer moods, calmer travel, and atmospheric depth.

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. cope - soar (v2.0) maps those parameters into its own visual language.
