You might like the book "The design of everyday things" if you haven't read it already. I find bauhaus design and understanding affordances etc much more interesting than abstract and non functional design. As another note, usability testing with irregular computer users with a skeuomorphic design vs a "flat UI" produces such crazy results in favour of skeuomorphism.
