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
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.
