A little late with this link, but here is an interview with David Bowen, an artist who uses natural systems like wind and flies to manipulate mechanical systems like lights and moving parts. He participated in ReceiverFest at Redux, which I so regretfully missed (they'd better do it again in 2012 if the world has not ended!).
I know the author, Rebekah Drysdale, from Tivoli Studios in Charleston but perusing her writing on Daily Serving was the first time I ever heard her critical analysis or thoughts on conceptual and non-object-based art. Charleston needs more of this and I'm glad she's posting.
