Does ‘brain-power’ make Enigma spin ?

The publication of an article by Zeki and his colleagues (1993) suggesting that the motion in the rings of Enigma is the consequence of cortical activity, and more specifically of area V5, has resulted in a debate between Professor Zeki and Professor Gregory, who believes instead that the motion is the result either of accommodative changes in the lens or of micromovements of the eyes. As an artist, I thought it interesting to contribute to that debate raised by the publication of Zeki9s paper and relate the steps that led me to the execution of Enigma.
