These pictures are intended to be cut up and resynthesized using GIMP or an equivalent tool to make repeating background tiles for web pages. They are primarily intended for use by students in my classes. They are hereby placed by the author / photographer, Don Colton, into the public domain and can be used freely for any purpose.
