Four laser beams are aimed at the fountain from a distance. At a height of three metres they follow the garden’s long sightlines for up to 500 metres, and refract in the mass of water. In combination with other lasers, moving geometrical figures of light form in the mist and surrounding trees, seeming to hover over fountain and spectators, changing dramatically according to atmospheric conditions. Contact with the ceaselessly rising and falling mass of water makes the laser beams visible as intensive surfaces of colour and points of light, which creates the fascinating illusion of the drops themselves as the light source.
Fountain Scan is conceived as an audio-visual composition together with Henke’s electronic sounds. It combines the art of engineering and the spirit of radical technical innovation with the artistic impulse in a consistent site specificity. For Henke the perfection and rigour of his Fountain Scan is a homage to the masterfully designed structure of the Großer Garten.
