In early March, Philips announced the winners of the revamped international lighting design CLUE Competition. The theme this year was Interface. The participants were asked to explore transformative potentials and to define unique lighting innovations that celebrate the activities of both the built and unbuilt communities. Incorporating the concepts of contact, transparency, transition, threshold, limits, dark/light, natural/artificial, the interface focuses on the spatial interactions influenced by exchanges between one and the other, and thereby distinguishing the two adjacent spaces.
