Modular~Matrix is an interactive light sculpture that visually depicts invisible radio frequencies and electromagnetic fields. It incorporates many light sensitive and emissive cylindrical devices. There is a base upon which people can build a relay of light by placing individual tubes on top of each other. Stacking the tubes allows light to move further away from its source. The individual cylinders mimic the light behaviour they received and altogether, create reconfigurable structures. Modular~Matrix helps visualize some of the radiations the human body emits and receives daily.
