Using SVG For Flexible, Scalable, and Fun Backgrounds, Part I
Several people use SVG for site design—mostly for topic icons. For instance, Sam Ruby, current HTML5 Working Group co-chair, uses SVG to annotate his weblog posts with topic icons. Erik Dahlstrom, from Opera, does the same, as does Jeff Schiller at Codedread. Jeff goes beyond icons, and incorporates SVG into his fisheye menu bar, as well as his website outliner graphic. The Emacs for Mac OS X web site is mostly SVG; resize the web page to see SVG scaling in action.
