SmileyFace

SmileyFace may serve as a simple example upon which other illustration types can be based. There is more up-to-date software here, such as GeologicTimeScale.

But, if you are interested in generating smileys, here is a tarball for the version presented at the 2005 North American Plone Symposium in New Orleans. Provided you get your system set up correctly, you should be able to select PNG, JPG, GIF, PDF, and SVG as targets.
