User interfaces remain one of the most fascinating elements of visual science fiction. They need to tell us something about what characters are doing (whether it's aiming a weapon or tracking a criminal, apparently the two most common activities in the future) and something about what the world finds aesthetically appealing, all in a way that's immediately understandable to people in the present. While most stay firmly in the future past, others have had a massive — some would say pernicious — impact on how we use technology in the real world. Even so, the designs often appear for only a few seconds onscreen, but the VisualPunke tumblr has collected them in an ongoing series of beautiful, often frenetic images from anime, video games, and blockbuster movies.
