Grid-11 uses various poligons and simple shapes to form an ellaborate cross.
Crosses are some of the most ancient human symbols. They have been used by religions (mostly known for Christianity) and can be interpreted in several ways. One of these interpretations is the symbolic union of divinity (the vertical line connecting the celestial or divine), and the world (the horizontal line connecting everything that surrounds us).
Grid-08, as with a few of the gridz we've seen so far, uses repetition over a diagonal axis. In this case half of the elements in the piece are duplicated and rotated 180-degrees.
