In architecture, a doorway represents the transition from one space to another. Portal visually displays this moment of transition as a two-dimensional plane penetrated by light. As viewers watch light pass through the diffuser screen, clean lines become blurred and diffuse. Designed by James Clar, Portal celebrates the concept of a spatial threshold with abstract lines of light that travel back and forth through a door, effectively “bouncing” around a room. In addition, an integrated motion sensor detects the presence of visitors and the emitters select a random color palette for the light.
