A hole in spring: the bass-masked radial portal that skipped the shader
Two panoramas at identical dimensions, one layered in front of the other. Cut a radial hole in the front layer, drive its radius with bass energy, and winter is visible through spring. No shaders, no post-processing pipeline — just winding-order arithmetic on a canvas clip path.
Bass amplitude into a radial alpha mask: audio reactivity as compositing, not particle spawning
Most audio visualisers route frequency data into particle spawn rates. Routing bass amplitude into a radial alpha mask between two panoramas is a different model — one where the music reveals a scene rather than decorating it. This is audio reactivity as a compositing problem.
Not a fade, a life: energy decay and perpendicular wobble in a music visualiser
The onset particles were launching correctly and dying identically. Tying an exponential energy decay to the perpendicular wobble amplitude was the difference between particles that travel and particles that live.
