Solar Fountain at the Farmers' Market
I take my solar fountain out for a walk from time to time at farmers' markets and in the city squares. Around the fountain are posters which display what I think are some of the rules of living within a restorative ecology. The splash of water makes a difference in public and children like to learn that they can turn the fountain on and off with the shadow of a hand.
