What the Mosaic tool does

/mosaic turns any image into a grid where each cell is one face of a Rubik's cube (full 9-sticker face, or split 6-sticker variant). The output is "how many cubes you need + the exact pattern each cube has to show". You can use it to physically build a wall art, or just admire the rendering.

Two styles

In "Whole-face" mode each cube contributes 9 stickers from one face — simpler but lower color density. "Split" mode breaks each cube into 6 orientations contributing separately, giving 6× density but requiring careful orientation. Switch between them at the method-choose stage.

How to use

1
Upload and crop
Drag or select an image, then adjust to the target aspect ratio in the crop stage (default 1:1). Higher-resolution, higher-contrast originals give crisper results.
2
Pick method and variant
First choose Whole-face / Split. Then pick grid dimensions (cols × rows = total cubes). The preview updates with sticker count and rough cost estimate.
3
Tune the palette
Default palette is the 6 WCA colors. Open the palette panel to tweak each color's RGB to match custom stickers or lighting. Changes recompute the whole image instantly.
4
Export the build plan
The export bundles: the overview render, per-cube 6-face facelets (read one face at a time from a fixed orientation), and a row-by-row build guide. Print or save as PDF.

Build tips

Use cheap stickered or solid-color practice cubes (smoothness doesn't matter); buy 5% extra to cover sticker loss or damage. Solve each cube to its target pattern AND label its position before mounting — once on the wall, adjustments are extremely expensive.
