About Pulse-Core

Pulse-Core is a browser-based sandbox for experimenting with a simple pulse simulation. Cells flip on and off based on neighbor counts and optional folding logic. Draw patterns, inject pulses and watch the results in real time.

• Dynamic grid adapts with the zoom slider (capped at 500×500 cells).
• Start/Stop controls with reverse stepping.
• Adjust pulse length, folding threshold and neighbor count while running.
• Brush, pulse injector and pattern stamper tools. Right-click any cell to erase.
• Color picker and optional flash effect.
• Save patterns as JSON and reload them later.
• Toggle debug numbers and grid lines.

How to Use

1. Open index.html in your browser.
2. Select a tool from the Tool dropdown and draw on the grid. Right-click to erase cells.
3. Press Start to animate the pattern and tweak the sliders as it runs.
4. Use Save Pattern to download your design or Upload Pattern to load a saved file.
5. The Reverse button steps backward through previous pulses.

Once loaded, the tool works entirely offline.
