Not all light artists like to stick to the shadows for their work. This graffitist is one of those who prefers to be at the literal (left) or approximate (right) center of things. A simple tag to the left is enclosed within a circle and puts the shadow of the artist at the center of the composition. In the right image the light seems intentionally designed to highlight his form, emphasizing it over the abstractions of the light sources themselves. (Source)
