of linear intersections both offer and resist any sort of visual resolution." Continuing with his investigation of grids and lattices Kidner experimented with various materials. He stretched and distorted elastic cloth on moveable wooden frames in geometrical shapes, in order to arrive at unexpected shapes, thus introducing randomness, instability and change into his art. He felt that constructive art needed to take into account disorder as well as order. Pentagon 1999 By 1999, chaos theory became a profound influence on Kidner's work and geometric abstraction in the form of Penrose pentagons reprinted on paper became a critical tool as a metaphor for ordering the chaos in the world. This was Kidner's response to the many dystopian world events, such as global warming, wars, ethnic cleansing, terrorism and intense nationalism. Kidner was intrigued by the fact that his pentagon patterns looked chaotic, like whirlpools that appeared and receded as he viewed them. His use of colour in these works was often random and whereas in his former work, colour was used to clarify the grid, now it subverted it. He now invested more value in unplanned elements in his work of that time. He wondered if there may be in chaos "some kind of order that perhaps we haven't yet recognised." In his last decade Kidner's work became more colourful and free. Titles such as Entangled Hyacinth Bulbs, 2007, Invasion of Iraq: Surprise Resistance 2007 and Particle Evolution: The End of the Tunnel at Cern.2008 indicate their subject matter. Kidner's distinguished career has included many honours, prizes and international shows. He taught at Bath Academy of Art, Corsham from 1962 to 1982 and was visiting lecturer at The Slade School of Fine Art from 1975 – 9 and Chelsea School of Art from 1981 to 1985. He co–founded the Systems Group with artist Jeffrey Steele and others in 1969. His work is in many important collections including those of Tate Britain, The Royal Academy, The British Arts Council, provincial galleries as well as in Portugal, Germany, Poland, Hungary, Vienna, Tokyo Russia and America. In 2004 he was elected as a senior Royal Academician. He was taken on by Flowers East in 2004. Latterly he was to see a considerable revival of interest in his work, as general critical interest returned to the abstract painting of the 1960s and early 70s. Death In spite of his progressive Cerebella Ataxia he continued to
