GOOGIE.
Google Googie architecture. It's basically perfect. You know how the Sims 1 soundtrack sounds? You know how a retro diner looks when it all snaps into place just the right way but there isn't a jukebox or a glittery red bar stool in sight? You're on the right track. Basically, in the event I am ever a deity, my domain will look as though a roadside motel built in 1966 forcibly erupted over the place.
