Check out Seb Przd's flickr set here. This guy is a master of using some extraordinary camera techniques to create some startling images. He has some great panoramic equipment coupled with some powerful photoshop plug-ins to create these gems. He has Escherized some pictures to create awesome spiral comped images like this one. His Stereographic Projections like the example pictures I have included can be seen here. And some great cloning work is found in this flickr set of his.
