A wall built with three different palettes
Each palette can hold unlimited blocks. The numbers indice their weight. For every 130 blocks placed (100 + 20 +10) there will be an average of 100 blocks from category 1, 20 blocks from category 2, and 10 blocks from category 3
Compact GUI to display more palettes at once
