GLOW Eindhoven 2014 featured “Zero Hidrográphico”, a light artwork by Gisela Motta and Leandro Lima in Eindhoven.
Brazilian artists Gisela Motta and Leandro Lima presented a work inspired by the sea in 2014. The title, Zero Hidrográfico, is the Portuguese term for the average sea level. In the Netherlands, we use NAP: the Normaal Amsterdams Peil (Normal Amsterdam Level) for the same purpose.
