The challenge was to create a monochromatic abstract mosaic using nature as a starting point. After finishing the work, I thought the top right hand side of the mosaic looked like part of a moon. That provided some context to the rest of the mosaic. Before I knew it I saw the essence of tides being pulled back and forth by the moon. Price is $350 plus tax in Texas and/or shipping.
