A great optical illusion painting, this man is playing guitar for the whole neighborhood! If you just look at the top of the painting it looks like a crowd of people. If you take the whole picture in you see the houses. Another subtle effect is that in the foreground, it looks like it is night time, but if you look at the clouds it looks like it could just be early in the morning. Also, the shadows aren’t really correct, are they? The shadow of the houses, and the man, and the windows, and the trees are all going in different directions!
