When Tuji sees a piece of modern art, most often he thinks duh. Now he thinks that he has been trying to appreciate the wrong thing. A lot of modern art is experimenting. For example, see that picture of juxtaposing rectangles of red and green? This plays on the perception of human brain which tries to tell objects part by using luminance, but then the red and green rectangles are of the same luminance. That picture in itself is not art. It is a by-product. The process of figuring out the luminance thing and making that picture is the art, much like behavioural art.
