We’ve all seen our fair share of spiral staircases but rarely do they make one do a double take like this collaboration between .PSLAB and architect Bernard Khoury. Designed for a residence in Beirut, Lebanon, the design brings light to the staircase and continues the spiral upwards to the ceiling.

The lighting concept mimics the spiral and gives a sculptural element to the often dead space at the top of most staircases. The light fans down and around and shines light down the winding stairs. Pretty smart, yet?
