Light is invisible and interreacts only through an object. Being a wave, it reveals the contour of that object, enlightening us. To me, basically, light is matter. Taking a picture is writing with light.
As a sculptor, I use various tools, shaping it into many incarnations:
Vibrations, reflections, undulations. Virtual movement. Materialization. Monochromy. Polychromy. Passing something on, but leaving the spectators free to enjoy their imaginations.
