Samurai Tree Invariants

The second piece that I saw at the Gabriel Orozco show was Samurai Tree Invariants. Having just viewed the Mobile Matrix, I was shocked that the two pieces were by the same artist. On a superficial level, the pieces are drastically different and seem to express similar ideas through contrasting mediums. The circular pattern is contained within a box, and is shown covering the entire wall space of the room. The tree is a series of circles in different sizes split with different colors down the diameter. The formation of circles is then displayed on top of a different rotating color scheme. Through out the piece the colors of the circles and the background changes. At first glance the color variation appears to be random but they are based on the movements of a chess piece. This is really interesting compared to Mobile Matrix because the graphite design on the bones was essentially without a method and designed through artistic opinion where as Samurai Tree Invariants had a rule behind the pattern. Both pieces challenge traditional design. People really don't draw on surfaces, in the home or other public spaces. There is a taboo nature to drawing on the walls and disrupting blank space that the Mobile Matrix touches on. Samurai Tree Invariants similarly questions color and patterns, what is the visual effect of having logic behind a pattern if any?
