ROBOTS by Emmett
This art shows rotational (spin, turn) tessellation symmetry. Each blue robot-shaped "tile" is a copy of its red brother, just rotated 180 degrees around the tip of one toe. This is a neat little tessellation because it has no gaps, and no overlaps, and the space between the robot-shaped "tiles" is negligible. All these elements are pretty unusual for a first-timer's tessellation. Well done, Emmett!
