Mosaic Series: Tetris
The Mosaic series is comprised of multiple smaller pieces to create the pattern.
Tetris is inspired by the shapes in the game Tetris. While these little squares may look random, each color is grouped into a tetris shape. Some of the pieces blend in together, as they are next to the same color, The pieces were placed on a graph in order to keep a gridded structure. This particular Tetris sample is made of 1/4" squares, but is available in any size.
