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.‎
