'Delta' is an interactive, modular lighting concept that enables users to adjust the amount of illumination in a particular space according to their need at a given time. It was inspired by the humble yet ubiquitous adapter plug and promotes human interaction with everyday products. Ananyaa Mital also initiates an emotional connection between product and user be evoking a sense of excitement and anticipation in having each module 'magically' light up as it is added to the tower.
