There are many images of the Vertcial Farm concept in my galleries as it has gone thru many changes over the years. Chris Jacobs, designer/concept artist, brought me on back in 2005 and we are still making changes. He has a great breakdown of the project here: http://www.chrisjacobs.com/
Along the way Rolf Mohr has done various designing updates and his great work is here: http://www.rolfmohr.com/
