David Castle paints abstractions infused with unexpectedly rich and vivid colors. His art is inspired by the variety of mountain and urban terrain he has explored throughout his extensive travels in North America and his years of living, working and traveling throughout Europe during his former career as a computer scientist. David draws from his exposure to the colors and shapes of these very different places as he combines paper, brush, oil and water, color, air, surface tension and gravity to create each painting.
