Great article! And I forgot about the Schwimmwagen, Germany's amphibious VW. It was a real masterpiece of innovative design. My father told me that he and the rest of his tank crew got hold of one at the end of the war and drove it around for the afternoon, taking it directly across a local river and back again. They were well impressed with its abilities, and hoped to use it to charm the local girls (the main thing on their minds at the time).
