Pop Art was a prominent offshoot of minimalism, a discipline that became renowned through the work of artists such as Victor Vasarely and Bridget Riley. Globally, many artistic movements resonated the artistic concerns of the above mentioned movements, often with regional specialties and nuance. In Italy, Lucio Fontana and Piero Manzoni established Spatialism, and in Germany the Zero group under the leadership of Gunter Uecker adopted similar ideas. The influential school of Existentialist Philosophy was an important source of creativity for creatives, with artists like Francis Bacon and Alberto Giacometti becoming known worldwide for their distinctive approaches to the human form and the anguish related to the human condition.
