An interesting spin off is DieselPunk. Steam has been replaced by Diesel Engines. 50s hard-boiled Noir meets CyberPunk. The computers are still big clunky Babbage Engines, but they are powered by Diesel Engine kept running by a short mechanic in grease covered overalls and a cap sporting the logo of a obscure engine manufacturer. You won't recognize the mechanic later that night when you are hitting the town. She's the one in the slinky dress, high heels, and a pistol that shouldn't fit in that clutch purse, but does.
