Graphicdesignblog.org has a great post of corporate logos with "hidden messages" that are also perfect examples to use when discussing Gestalt psychology. From closure to figure-ground to continuity (and more!) here are 25 examples that would be great for students to dissect.
I used the FedEx logo in class earlier this year -- I found it on a page of Gestalt examples and had no idea what principle it represented! When I finally saw the arrow I knew I had to use that example in class.
