A couple hours after mentioning Outsider Software I see a Call for Artwork at XML 2004.
Past exhibits (see XML 2003 Artwork) have included XSL-FO specification snippets done in calligraphy; needlework on the subject of the XML Infoset; hierarchical quilting; handmade paper printed with XML-derived bar codes; and more.
