Yaacov Agam is an Israeli sculptor and experimental artist best known for his contributions to optical and kinetic art. Agam's work is usually abstract, kinetic art, with movement, viewer participation and frequent use of light and sound. His works are placed in many public places. His best known pieces include "Double Metamorphosis III" (1965), "Visual Music Orchestration" (1989) and fountains at the La Défense district in Paris (1975) and the "Fire and Water Fountain" in the Dizengoff Square in Tel Aviv (1986). He is also known for a type of print known as an Agamograph, which uses barrier-grid animation to present radically different images, depending on the angle from which it is viewed.
