My son's dog Oxy is a lot of fun. When I saw him dragging stones around in circles and drawing with them I decided to get him some soft ochre and natural chalks, and hey presto, his drawings became manifest on the patio. He specialises in circles and he has covered the entire patio in his drawings. This vimeo is of his latest work, which has since washed away in the rains of 9th July 2013. The music is Spacey Club from iLife. I want to thank Dave Nixon of ABC Open for the fabulous final editing and tutoring in how to make a video. Thanks Dave you are a maestro!
