In the artwork Pareidolia* facial detection is applied to grains of sand. A fully automated robot search engine examines the grains of sand in situ. When the machine finds a face in one of the grains, the portrait is photographed and displayed on a large screen. Pareidolia was developed for Sea Art on the isle of Texel, commissioned by SEA - Science Encounters Art. The production was supported by the Creative Industries Fund NL.
