Sumi-e Lambda λ and Delta Δ are variations of the same concept, a design born from the breakdown of a square to create new geometrical structures. By cutting out a sub-module on the inside of a classic mosaic tile, small shapes were created; these were triangular for Delta and square for Lambda.

The design changes, depending on how the elements are positioned, giving rise the random and organic qualities that lighten the surfaces on which these are placed.
