Green Man 'Einstein's Garden SketchCrawl'

Some images from my stint leading the 'Magical Mystery Draw' for the Green Man Festival's science themed area, Einstein's Garden.  The basic drill was that I gave a everyone a handed printed sketchbook and pencil (I also lugged round half of my own kit for them to try), showed them the wonders Einstein's Garden and mercilessly forced them to draw them. Who'd have thought that could be so relaxing?
