Holger and Juliane have a cool repository of SVG related resources, nice drawings in svg and (gui) components done in XML, XSLT and SVG. Among those are e.g. Login-Boxes rendered in SVG or various versions of bar charts processed in SVG.
All this is available at www.treebuilder.de.
Note that for visiting the site, you need a browser that is svg capable like Firefox or a SVG plugin for the browser (as for Apple Safari).
