I started my career making light-objects. “Structures in Motion, Reflections, Transparencies and Poly-Chromatic Projections” is the title of an installation using natural and artificial light, creating projections into three different spaces. As the three groups of optical glass prisms slowly turn, the projections of the spectral colors change form and disappear and reappear in the three adjacent rooms. The prisms turn so slow and with different speed that it will take a full two weeks for the installation to get back to its original position.It was a joyful experience to be able to make this light-sculpture with the help of construction-superman Juul Bonnet.
