My paintings are often sparked off by something that strikes me visually. Without a visual stimulus, the result seems arid. I think some mathematicians believe maths needs a link with reality. I use arithmetical sequences and geometry to distribute motifs, shapes, colours; e.g. Golden Section, prime and Fibonacci numbers and eccentric constructions. I make subjective decisions about which sequences and constructions to use. One idea can produce a series of works. Interrelations within the work and to the whole are aimed at a calm unity. Some examples follow of how work is developed.
