From around 1959, Moon had been experimenting with ballet and modern dance, choreography, poetry and painting alongside his day-job in advertising.
In 1962, Moon won The Associated Electrical Industries Prize for Sculpture, a competition that was judged by his friend Phillip King, the British sculptor.
At this time he was living and working in Chepstow Road, West London and had his first solo show at the nascent Rowan Gallery in Knightsbridge.
Reoccurring motifs and elements within his paintings included grid-like forms composed of vertical, horizontal or diagonal lines.
Drawing was a central part of his practice and he used pencil, pen and pastels incessantly on A4 letter-writing paper to develop ideas for works.
His peers included John Hoyland, Bridget Riley, Ian Stephenson, Bernard Cohen, Patrick Caulfield, Phillip King and Anthony Caro.
Moon died aged 39 following a motorcycle accident at Robin Hood roundabout on the A3 whilst commuting back from Chelsea to Kingston on 30 November 1973.
