It featured iconic landmarks along the Singapore city skyline and took a team of close to 50 artists, teachers, and students 11 days to complete it.
Anamorphosis, in the visual arts, an ingenious perspective technique that gives a distorted image of the subject represented in a picture when seen from the usual viewpoint but so executed that if viewed from a particular angle, or reflected in a curved mirror, the distortion disappears and the image in the picture appears normal.
Derived from the Greek word meaning “to transform,” the term anamorphosis was first employed in the 17th century, although this technique had been one of the more curious by-products of the discovery of perspective in the 14th and 15th centuries.
Artists and architects in the 21st century continued to experiment with anamorphic designs. In 2014 Swiss artist Felice Varini—known for large-scale anamorphic installations—created Three Ellipses for Three Locks, for which he painted three ellipses, segments of which covered roads, walls, and nearly 100 buildings in the historic centre of the city of Hasselt, Belgium. The design became coherent only when viewed from a particular vantage point in the city.
