 The Quarter Round Mosaic is a geometric assembly exploring the influence 
            of color in an arbitrarily generated field.

            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.

            alternate palette with dense arrangement. Quarter rounds are slso 
            specially arranged so that their rotations combine to form circles.

          |  | The result is a mosaic with semi-smooth color blends. The negative 
            space of the quarter round in its grid cell weaves an additional dimension 
            to the structure.
