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).
Experimenting with car light trails and long exposure photography while on a bus ride back from a Vegas trip can be quite rewarding. I was surprised so much definition and detail was possible even while free handing it.
