Op art

Abstract art is art that does not attempt to represent an accurate depiction of a visual reality but instead use shapes, colours, forms and gestural marks to achieve its effect

Minimalism is an extreme form of abstract art developed in the USA in the 1960s and typified by artworks composed of simple geometric shapes based on the square and the rectangle

Kinetic art is art that depends on motion for its effects

Short for neo-geometric conceptualism, the term neo-geo came into use in the early 1980s in America to describe the work of artists who criticized the mechanisation and commercialism of the modern world

To coincide with the display, Tate Etc. talked to the Venezuelan-born artist Carlos Cruz-Diez (born 1923) about his early exhibition at Signals London in 1965, his works and his lifelong exploration of colour

Tate Etc. invited a selection of contemporary artists to choose a favoured work from a fellow artist – past or present. Here, Fiona Rae discusses Bridget Riley's Hesitate 1964

Oskar Fischinger's animated films that were partly influenced by the poetic abstraction of Kandinsky's paintings were among the first to mix high art and mass culture.
