Create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts.

The user wants me to create a single-page web app with a fireworks display. The requirements are: 1. Full-screen canvas 2. Clicks launch shells 3. Shells explode into gravity-affected particle bursts 4. Particles should fade 5. Everything in one self-contained HTML file 6. No external resources or network requests 7. CSS in <style> tag, JS in <script> tag I need to create an HTML file with: - HTML structure with a full-screen canvas - CSS for styling and making canvas full-screen - JavaScript for: - Canvas setup and full-screen handling - Mouse click event handling - Firework shell physics (launching upward) - Explosion particle system with gravity - Fading effects - Animation loop Let me structure this: 1. HTML with canvas element 2. CSS for full-screen canvas and basic styling 3. JavaScript for the fireworks simulation For the fireworks physics: - Shells launch from bottom where clicked, go upward with some velocity - At peak height, explode into particles - Particles affected by gravity (downward acceleration) - Particles fade over time - Use requestAnimationFrame for smooth animation
I'll create a fireworks display web app for you. This will be a single HTML file with a full-screen canvas where clicking launches fireworks shells that explode into gravity-affected particle bursts.

I've successfully created a fireworks display web app in a single HTML file. The app includes: 1. **Full-screen canvas** that automatically resizes with the window 2. **Click interaction** - clicking anywhere launches a firework from the bottom to that position 3. **Realistic physics**: - Firework shells launch upward with initial velocity - Gravity affects both shells and particles - Shells explode at peak height or when velocity becomes positive 4. **Particle effects**: - Each explosion creates 50-100 particles - Particles have gravity, friction, and fade over time - Both shells and particles leave fading trails 5. **Visual features**: - Gradient night sky background - Multiple random colors for variety - Semi-transparent fade effect for smooth animation - Auto-launching fireworks for continuous display 6. **Complete self-containment**: - All CSS in <style> tag - All JavaScript in <script> tag - No external dependencies or network requests The file is now ready at `/tmp/ws/index.html` and can be opened in any web browser to enjoy the fireworks display!
I've created a complete fireworks display web app in `index.html`. The app features: - **Full-screen canvas** with automatic resizing - **Click-to-launch** fireworks from the bottom to your click position - **Realistic physics** with gravity-affected particle explosions - **Beautiful visual effects** including: - Fading trails for both shells and particles - Multiple random colors for variety - Smooth fade effects instead of harsh clearing - Auto-launching fireworks for continuous display Open `index.html` in any web browser to start clicking and launching fireworks! The app runs completely sandboxed with no external dependencies.
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
Clicking, dragging, wheel, enter/space, and WASD all launch colorful fireworks with fading particle bursts and gravity trails over a dark sky.

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.
