15:04 Oliver O'Keeffe is giving an extra presentation about his work as a visual artist. He separates the creative moment into the "idea" and the "aura" that emanates from the idea. This presentation provoked a discussion about how different moments, the past the present and the future can or not happen at the same time. His is an original and unplanned response to today's marathon's theme. Thank you very much to Oliver for preparing something to say in such a short time (1 hour and 4 minutes).
