Create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts.
thinking
The user wants a fireworks display on a full-screen canvas. Clicks launch shells that explode into gravity-affected, fading particle bursts. No external resources, all in one index.html file. Key components: 1. Full-screen canvas 2. Click to launch shell 3. Shell goes up and explodes 4. Particles with gravity and fading 5. Self-contained in one HTML file I'll create: - HTML structure with canvas - CSS for full-screen (no scrollbars, canvas covering viewport) - JavaScript for: - Canvas setup and resize handling - Shell class (projectile going up, then exploding) - Particle class (physics with gravity, fading) - Animation loop - Click/touch handlers Physics: - Shell launched with initial velocity upward - Explodes after some time or when velocity slows down - Particles spread out with random velocities - Gravity pulls particles down - Air resistance/friction slows particles - Particles fade out over time Visual style: - Dark background (night sky) - Bright colored particles - Maybe some glow effects using canvas shadow properties Let me write this code.

The fireworks display has been created. Let me verify the file was written correctly and test it by reading it back.

thinking
The file was written correctly. It contains: 1. Full-screen canvas setup 2. CSS for full-screen display with black background 3. JavaScript classes for Shell (rising projectile) and Particle (explosion debris) 4. Physics with gravity, friction, and fading 5. Click/touch handlers to launch shells at clicked coordinates 6. Auto-launch feature for ambient fireworks 7. Trail effects using semi-transparent black overlay The implementation is complete and self-contained in one HTML file with no external dependencies.
Created **index.html** with a complete fireworks display featuring: - **Full-screen canvas** that resizes with the window - **Click/touch to launch** shells from the bottom toward your click position - **Physics simulation**: gravity on particles, air friction, velocity-based trails - **Visual effects**: glowing particles, HSL color variety, semi-transparent trails for motion blur - **Auto-launch**: random ambient fireworks every so often - **Mobile support**: touch events work alongside mouse clicks The shells arc toward your click position, then explode into 40-70 fading particles that fall under gravity. Open the file in any browser to test it out.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Animated fireworks with colorful gravity-affected particle bursts trigger on click and even other keys/inputs, with smooth trails and fades.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
