My brother has put the film he and Sara made together a couple of years ago online. It's called Perennial and is a beautiful meditation on nature and a year in their life spent walking around Chicago (and Georgia) filming water and leaves and snow and ducks. Apparently there is a sequel in the works. I'm addicted to embedding, but you can see a larger version on the Vimeo site.
Simon would have to confirm this, but I think that might be my autoharp making a cameo on the soundtrack. Not played by me of course, but surely this justifies an associate producer credit!
