Over the years I developed a decoration system that reflected a lot of patterning and surface textures that I saw on African vessels. Most of the patterns I first used were direct translations of African patterns. I still draw on that source. After ten or so years of looking primarily at African art, I started becoming curious about other cultures that had a tradition of geometric design on their work. I started looking at textile design, body decoration, architectural details, especially Islamic tile designs which rely heavily on geometry. — David MacDonald, in 2008 interview
