I was inspired by Don Stewart's Blog posting "The Lambda Revolution" to create a tee shirt design on this theme. Samples are available from CafePress at http://www.cafepress.com/l_revolution , but the designs are freely available. If anyone wants to send them to a more local tee-shirt printer than CafePress then let me know and I will email the SVG files.
