Mi Young Yeo of Korea's Gocce Design has created the kaleidoscopic Let It Snow, a user-friendly ambient lighting system. Turn the central crystal like a knob or dial and control the amount of coloured light that is reflected on the mirrored backdrop. Each crystal produces a beautiful snowflake of light. Hidden Art features lighting that is just as intricate: work by Yu Jordy Fu. Yu Jordy Fu's Cloud Lamps are made of recycled paper and reflect the ancient Chinese art of paper-cutting that was used to record memories and events. The Cloud Lamps are shades treated with a non-flammable spray and are designed to be used with energy-saving bulbs. And Stockholm's Maria Larsson and Maria Olevik of In Every Tree create sculptural lighting out of bone china and mixed media. Books lie stacked on a table or stand upright on a shelf.
