Rachel Rieder- The Escher Form

The blog isn't letting me upload the image for some reason, but I chose a piece by Escher, which is a black and white of birds "becoming" fish. As the viewer's eye travels down the page the previously negative space turns takes on a form from the abstract shape it once was into a new object. The transition is done gradually, with an expert degree of subtlety and detail. Escher's work never ceases to amaze me.
