Greenbaum notes: "Pestoni layers different actions on top of each other to create a harmony, or a two-dimensional three-dimensional space. How far back do these go? How many layers are there? That number seems infinite, but you can’t go on forever—at some point you stop, and then you get a fleeting glimpse of something. There is no figuration here, and no grid either, just the arm moving up and down, creating a forest. The work keeps bugging me because it is so hard to sum up. It doesn’t scream out at me, drawing attention to itself."
