Retro Futurism
Retrofuturism is a movement in the creative arts that blends an old-fashioned, "retro" style with futuristic technology. It's a way of looking back at how people in the past, particularly from the early to mid-20th century, imagined the future would look.
The core idea of retrofuturism is "the future that never was." It captures a sense of nostalgia for a future that was once optimistically dreamed about, but which never came to be in the way it was envisioned.
