Confetti Cannon

Ochre festival-paper palette: broad confetti rectangles fire from bottom corners, tumble and flip. First input stops automatic launches; a manual burst keeps its finite cleanup. Reduced motion starts with a populated paper field.

When to use it

Celebration moments, success screens, gamification rewards, party or event landing pages.

When not to

Productivity or focused reading contexts — constant auto-firing is highly distracting. Remove the auto-fire interval for production click-only use.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change the palette to pastels by replacing pal with ['#ffb3c6','#ffd6a5','#caffbf','#A19A87','#f8d8b4','#ffcf9f'], and increase gravity from 0.13 to 0.18 for faster fall. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

color palette (pal array)
gravity constant (0.13)
particle count per burst (18 + random*10)
auto-fire interval (55 + random*30 ticks)
paper size (width 6–10px; height 4–7px)
theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

visibilitychange stop/play guard
reduced-motion branch (single static burst pre-rolled 20 steps)
DPR-aware canvas sizing
110-particle cap; auto launches stop adding once 100 particles are present
theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
demo-v1 preview lifecycle: initialize demoEnabled from window.__foreverPreview and stop attract work on the window forever:interactive event; retain manual feedback, settling, cleanup and explicit sessions

Known limitations

Auto-fires from corners continuously — remove the t>next block for click-only production use
Particle cap (110) can cause burst suppression under heavy click-spam
No aria role on canvas — click interaction is invisible to assistive tech
State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
