Bridget Riley is one of the most significant and original painters of our time. The Sunley Room exhibition will enable visitors to investigate how Riley’s work relates to the National Gallery Collection.
Recent work
The exhibition focuses upon Bridget Riley’s most recent paintings. Two of Riley’s works will be made directly on to the walls of the exhibition space. Riley and her studio will create a new wall drawing, ‘Composition with Circles 7’, especially for the longest wall of the Sunley Room. In addition a version of the wall-painting, ‘Arcadia’ – last seen at the major 2008 retrospective in Paris – will be recreated on a larger scale.

Op Art
Op art, also known as optical art, is a style of visual art that makes use of optical illusions.
"Optical art is a method of painting concerning the interaction between illusion and picture plane, between understanding and seeing."
Op art works are abstract, with many of the better known pieces made in only black and white. When the viewer looks at them, the impression is given of movement, hidden images, flashing and vibration, patterns, or alternatively, of swelling or warping.

Kaleidoscope
A kaleidoscope is a tube of mirrors containing loose coloured beads, pebbles, or other small coloured objects. The viewer looks in one end and light enters the other end, reflecting off the mirrors. For a 2D symmetry group, a kaleidoscopic point is a point of intersection of two or more lines of reflection symmetry. In the case of a discrete group the angle between consecutive lines is 180°/n for an integer n≥2. At this point there are n lines of reflection symmetry, and the point is a center of n-fold rotational symmetry. Source:

Geometric Abstraction
Geometric abstraction is a form of abstract art based on the use of geometric forms sometimes, though not always, placed in non-illusionistic space and combined into non-objective (non-representational) compositions.
