Pattern Editor

The Pattern Editor is a dedicated tool for designing your own balloon pattern. You can already pick colors and patterns in-game, but this tool lets you go further — painting a grid cell by cell, just like a real manufacturer's envelope diagram, or splitting cells into triangular panels for even finer control.

What it can do

• A 3D preview, drawn with the same math the game uses, that you can drag to rotate and inspect
• Start from a built-in pattern (alternating, horizontal, spiral, and more) as a base to adjust
• Click to paint individual grid cells or triangular panels in any color you like
• Load a reference photo or diagram alongside the editor to trace an existing pattern
• Copy the finished design as a short share code — send it to a friend and they can load the same pattern in-game

How to use it

1. Choose whether to build from a formula or paint the grid/triangles directly
2. Pick a color under "Palette," then click grid cells or triangles to paint them
3. Check the result in the 3D preview as you go
4. Copy the share code and paste it into the game's balloon pattern field

This tool uses the exact same formulas and share-code format as the game itself (balloon-appearance.js) — directly, not a reimplementation. If the game's code format ever changes in the future, this tool follows automatically, so the two never fall out of sync.
