Here's a really cool series of Dieselpunk concept art created by CGHUB artsit BjornHurri. These feature some great character and vehicle designs. For those of you not familiar with dieselpunk, it's based on the "aesthetics of the interwar period between the end of the World War I and the beginning of World War II. The genre combines the artistic and genre influences of the period (including pulp magazines, serial films, film noir, art deco, and wartime pin-ups) with postmodern technology and sensibilities." What do you think of the designs?
