Dieselpunk is a genre similar to that of its more well-known cousin "steampunk" that combines the aesthetics of the diesel-based technology of the interwar period through to the 1950s with retro-futuristic technology and postmodern sensibilities. Coined in 2001 by game designer Lewis Pollak to describe his role-playing game Children of the Sun, the term has since been applied to a variety of visual art, music, motion pictures, fiction, and engineering.
