The installation Delta Phi is based on the principle of caustics – the way light refracts on water.
The chrome-plated surface was computationally designed and 3D-milled. Encoded into its facets
are hidden Greek letters, which become legible in the surrounding room with the help of reflected surface light.
Phi is the sign for luminous flux. Delta stands for change and movement.
The piece was produced as a prototype for the "River Is..." installation at the Four Rivers pavilion near Gwangju, Korea.
In 2013 Delta Phi was exhibited at MADE, Berlin. Delta Phi is part oft the permanent exhibition of the Swiss Science Center in Winterthur.
