This is Paul Klee's "Head of Man, Going Senile," and I think it is a great example of Gestalt ideas.  As Behrens said, "a whole is not simply the sum of its parts, but a synergistic 'whole effect,' or gestalt."  Looking at this painting, we see clear parts.  We see clear shapes, some of them recognizable geometric shapes, like the two red circles and the different colored squares.  But this painting is not simply a combination of circles and squares.  The shapes interact with each other, as does the color, and creates an image, a "whole effect," a "gestalt."  Many of the things Arnheim has discussed are illustrated in this painting, and play a part in creating the "gestalt."  It is the differences in color that create the shapes because the different colors next to each other have created contours.  While the painting is not exactly symmetrical, I would say it has a sense of balance because there is an equal weight distribution on both sides.  The head tilts to our right, but, as you can see, the "body" of the man is smaller on the right than the left in order to compensate, thus balancing the picture out.  Also, what plays a huge part in "reading" this picture is our past visual experience.  As Arnheim says, "Every visual experience is embedded in a context of space and time" (48).  Just as we can recognize figure 19 in the chapter on shape as a face, we recognize this image as a face, because of our familiarity with the human face.  Also, the title of the painting plays a part in the process, just as our interpretation of the Picasso painting put up is influenced once we learn it is a man playing an accordian.  Figure 21 in the chapter on shape can be seen as diagonal lines with two white triangles in the upper left and lower right corners, but once we are told it is a giraffe passing through a window, our view of the image changes.  In the same way, the title to this painting influences the way we see it.
