Images of utopian futures have been springing up all over San Francisco, and they're the work of muralist Mona Caron. Her Church Street mural (near 15th. street) includes a utopian future straight out of Ecotopia. And now her new Noe Valley dyptich includes bicycle-powered electricity, "Relaxed transit" and a giant urban Seed Bank. She's unveiling the finished product on Saturday, Sept. 27 from 2 to 5 PM.
