Mosaic digital design : The Quarter Round Mosaic is a geometric assembly exploring the influence of color in an arbitrarily generated field. CLICK the completed mosaic to begin anew. Each mosaic is generated over time so that shapes placed earlier in the process have more influence on the composition. At a regular interval, a quarter round shape is placed in some empty grid space. The quarter round immediately polls all of its neighbors (existing or not) to determine the mean average color of the region. It then transforms itself to that color and rotates to some random orthogonal orientation. Figure c. alternate palette with dense arrangement. Quarter rounds are also specially arranged so that their rotations combine to form circles. The result is a mosaic with semi-smooth color blends..
