Stumbled across this artist's work via Saatchi Online, there are some amazing images constructed from modern/industrial images and manipulated to suggest the natural environment, such as Above the Timberline 5 or River Flows in You.  I like this idea of melding the two environments and it it feeds the ideas that arose from the conference considering the aesthetics of sustainability. This is what I was starting to try to do with the last videos - using the images of concrete and plastic balls to create a different planet/world similar to the eye/sun video.
