“All you need. Nothing more.” is a kinetic lighting work which employs wavelengths of light at each periphery of the visible spectrum. They are the colors of light that are most used in the process of photosynthesis. The work considers the relationship between us and the sunlight which provides the energy that is the basis for almost all life on earth. The natural systems which convert this energy into forms we humans can consume are intensely complex. In recent years, here is an increasing variety of human endeavor to grow plants indoors by using electric light. However, given a strict and steady diet of CO2, H2O and electromagnetic radiation at 460 nm and 740 nm, do those plants long for the slow-changing hues of a sunset? Or for the pale hours of early morning? What becomes of the greens and yellows and the great subtitles of the rest of the spectrum? And, if we were forced to flee a newly-hostile environment and grew a tree underground, would we become nostalgic for a time when nature nurtured us? Or would we sit in that subterranean pinkish glow and bask in the ingenuity of our efficient system which gives all we need, and nothing more?
