Javascript Injection

I'm currently working for a client, and one this project they want users to be able to use HTML, but ofcourse i don't want them to be able to do some 'dodgy' stuff, so i created a little test engine to remove every trick i know in the book about injecting javascript into systems that allow HTML to be used, but not JS.

http://www.gzevolution.net/self.php

I was wondering if anyone here can get ANY js to execute on that page, and if you can, what html code did you input?

Yes, the client knows this is a bad thing, but he won't take no for an answer, so all help is appreciated, i don't want to leave security hole's in the system.

Thanks people,

It is not a VB3 engine, just a parsed copy!
