Illusionism

An optical illusion is an artistic technique that forces the viewer to see what is not actually there, due to the peculiarities of human perception. In visual art, optical illusions are often used to create volume on a flat surface, a sense of movement, or transformation of figures. A vivid example is the work of Victor Vasarely and Bridget Riley, whose paintings 'moved' before the public's eyes without any animation!

In sculpture, the 'Anonymous' statue in Budapest is considered a hit: from certain angles, it seems the figure has no face at all. The use of optical illusions enlivens even the most austere interior: for example, when a porcelain vase is painted in such a way that it appears much smaller (or larger) than it actually is. Illusions require skill and careful planning, since the slightest breach of perspective will destroy the entire artist's intent.
