I wrote this letter after visiting one of their museums, in Los Angeles, California. I never heard back from them. 90 Eglinton Ave. My unique procedure was written about in Clifford Pickover's Journal of Chaos and Graphics some years ago. Leaves on trees are randomly placed as are the branches.
Houses are of random width but a standard height.
The round tree images were originally drawn on the computer and then the exact locations and other features were randomized, while the pine trees and other images are purely computer generated. Some of these patterns take minutes to draw while others in the enclosed batch took over an hour. There are currently about five basic patterns. I have given away close to 20,000 of these drawings and each one is unique. These could be photographed or litho printed or something for display since the colors on these samples will fade fairly quickly in bright light.
