Andrew worked on Complex Brain; Spreading Arbour (2004) with the neurologist Dr Richard Wingate, of the Developmental Neurology Department, Kings College, London. Together they created a time-based video work based on the development and changes in the growing brain; looking specifically at the migration of neurones out of the brain and into the body. The work uses two video projectors circling a double-layered 8-meter circular voile screen in opposing directions to project the animated drawings of the neurones streaming through the body. A Wellcome Trust Medicine In Society Award funded this work. The work is 25 minutes in duration. This work was first shown at the British Association Festival Of Science, Exeter, in 2003. The exhibition also included the works Magic Forest and Calcium Caving.
