In order to design enduring and vibrant exterior artwork I began experimenting with tile mosaic. The attraction to tiles is primary though. Arranging squares of color is like a puzzle, it brings up associations of play. The ancient art of mosaic connects to the digital with each tile an analog to a pixel. It requires interpreting the colors in an image or photographic source into a block of material with physical qualities, alternating cool and warm hues, opaque and transparent, dark and light, smooth and textured. The selection of tiles becomes paintbox and palette.
