It's like looking at something under a microscope as opposed to giving it a casual passing glance. The closer you look, the more you see, and the more you see, the more fascinating it gets.
This reminds me of an exhibition of Pablo Picasso's Las Meninas that I saw over the summer. Pablo Picasso drew about fifty paintings of his interpretation of the original las meninas painting and by doing this, he created a unified theme and I assume analyzed the painting thouroughly but for the viewer it was just mass obsession and repetition
