An analogue yet interactive wall installation, designed and built for EKZ Zurich in 2018. The 2×2 m panel uses over 500 light switches, allowing EKZ employees to “draw” images or write messages whilst walking by. The panel functions entirely without electricity—when “switched on”, the light switches reflect surrounding light sources, revealing a pixelated image. This playful installation transforms a utilitarian office environment into an interactive canvas, encouraging spontaneous creativity and collaboration amongst employees.
