Sfirot
Sfirot is a 10 m. high steel construction in a decagonal water basin of polished black granite with a big 40 tons black granite rock resting on it. The lower part of the rock is faceted, and 10 polished spherical hexagonal granite mirrors reflect the light from holographic gratings built in the basinwall under water. From beneath in the center of the rock water is running down a heavy anchorchain to the basin. Because of the watermovement the light will be twinkling in the mirrors and at the same time it will be shifting colors horizontally according to the spectators' movement.
The reconstruction light comes from fiber optics. The gratings and mirror angles have custum designed geometry that the reflected light can be signalled to strategically chosen places in the neighbourhood.
