Title: Cursor Comets — Night Sky Playground
Prompt: A full-screen night sky where the cursor becomes a comet with a burning head and cooling tail. Drift to paint across static stars, click for meteor showers, and press C to redraw glowing constellations. Deep-space palette of ice blue, gold, rose, and mint.
Design: Fixed canvas universe with twinkling starfield and constellation lines beneath floating HUD panels; control deck offers colour swatches, tail-length and gravity sliders, and sky mode select with live particle and FPS chips.
Visual techniques:
- Canvas particle engine with velocity, gravity, and decay
- Fading fillRect trails for comet persistence
- Twinkle-modulated starfield with constellation polylines
- Screen-blend cursor ring tracking the pointer
- Reduced-motion fallback to a calm static starfield
Interaction model: Pointer movement spawns comet particles; clicking the sky or Space triggers a shower, C redraws constellations, sliders tune tail length and gravity, swatches recolour comets, and Clear empties the sky.
