Drag corners onto the wall. Drag inside: slide print. Wheel: scale. Alt+wheel: rotate. Shift+wheel: tile width. Shift+Alt+wheel: tile height. Tab cycles corners, arrows nudge (Shift 10, Alt ¼). Esc closes calibrate, Esc again stops projecting. Zero the projector's own keystone first. Camera solves the warp for you: mark the projected crosshairs, mark the wall's own corners, then Fit corners.

One strip, every lane; Live the day walks it by itself; the sliders override until the next scene.

Dapple — a canopy cookie in front of the projector; Dapple gust how far disturbances lean it; Frame dirties the world’s edge

Ecology

Butterflies and moths are a stochastic Lotka–Volterra pair: butterflies breed to the print’s capacity, moths feed on them; the dials are the rates, the mix is simulated

Raster edge — nothing blooms within the margin of the frame’s edge; light fades over the band; sparks slow in it

Light only for the wall; Project is fullscreen with the saved warp (Esc leaves); Calibrate drags the corners; Repeats, Fit, Render make the raster follow the wall (README, Resolution).

A landing lights its bloom: butterflies amber, moths moonlit blue; white blooms take the fill, pink ones the outline. Presets and share links carry all of it.
