http://www.classiccar.com/wordpress/2008/the-art-of-michael-ulman/ Ted writes about the work more than I do, but this is such an impressive artist!
we both link you to the artist's website for his full gallery of past and present portfolio. I have bigger pictures due to the magic of photoshop, remember to click on them for the full size (Micheal didn't put large size pictures on his website) http://www.michaelulman.com/index.htm
I was reminded about this cool artist when I looked at http://www.darkroastedblend.com/2008/02/robots-in-arts.html
