“Since 2000, the hugely popular 5k competition has been challenging web developers to create the most innovative and stimulating work possible in less than 5,120 bytes.
Entries for the 5k can include virtually any client-side technology in use on the web, including Flash, DHTML, Java, SVG, X3D, and weirder things that you need plug-ins for. But remember, if the judges can’t see it, they will probably give you a very bad score. No server-side processing is allowed. “

I love that they don’t tell you about any browser standards. The judges could be using anything and you either have to plan for that, or disregard it and hope for the best.
