Hereafter is a piece by UVA, a group whose physical computing work is really good and has super high production value. It is one of a few of their pieces based on “mirror” ideas that involve the theme of interacting with video history. As with all their work, the high quality of their finished product, and thought given to context and aesthetics lends a magical nature to the technology that is more bang and less whiz.
