A SMALL FIELD GUIDE

Follow your curiosity.

Afterlight is a light instrument. There is no score, no finish line, and no right way to play.

Pull the light
Hold and drag anywhere in the field. On a keyboard, focus the field and use the arrow keys.
Make a little weather
Send a pulse with P. Switch worlds with 1 2 3. Find a new variation with R.
Find your rhythm
Turn sound on for an ambient synth that responds to your gestures. Space pauses motion and sound. H hides the controls.
Keep a piece of it
Save a PNG, or share a link to your world, palette, variation, flow, and energy. Motion starts afresh when a link opens.

Made from math, light, and synthesized sound. Everything runs in your browser. No accounts, uploads, or tracking. Reduced motion starts paused.
