Behold the tank as imagined by designers in California back in 1917. The design steals from the British tanks present on the battlefields of World War I with one exception, a single front wheel and armor that would make it utterly useless on the battlefield. Even the article in Popular Mechanics stated that the California design would be hopeless in a landscape of shell craters, obstacles, and trenches. Still, it does look a little like the love-child of H. G. Wells and Leonardo Da Vinci. Worthy steampunk fodder, I'd say.
