The Deep Time Walk. I have written a poetry/drama script based on a scientific text by Doctor Stephan Harding of Schumacher College, Devon. It's a walk from 4.6billion years ago to the present. Each metre you walk is a million years. The dialogue is between a Fool and a Scientist, who describe the things they see, as they walk along, argue, and fall in and out of love with the idea of Gaia. James Lovelock has done the walk, or listened to it, and he likes it! It's available from the App store for £2.99
