Logan's Run (1976) imagines a domed pleasure-city where life ends at thirty, signalled by a crystal in the palm that blinks red on Lastday. Production designer Dale Hennesy built it from curved acrylic, chrome, and shopping-mall-modern white interiors — a bright, optimistic future hollowed out by ritual death.

This design system distills that world: a cool clinical mall-white ground, geometric squared signage type, and a single signature red lifeclock crystal as the focal accent, flanked by the clock's own cycle of yellow and green.
