Blurry Code

While hunting around for Compiz documentation yesterday (if anyone knows of anythinng more than Francis' Walkthrough then please show me!) I stumbled upon this plug-in (a text version here)

It aims to blur what is behind any transparent(translucent) object - so for example the desktop icons underneath a semi transparent window. It sounds like a great way to reduce the clutter induced by too many semi transparent windows!

However, the plugin is not complete, and doesn not work :(. I emailed the author to ask about its development and got the following response:

Blurring behind translucent windows was the original intention. The
plugin does not work, and will unlikely be finished anytime soon. I
got frustrated with the lack of documentation for compiz plugins, and
the fact that I didn't have the GL_ARB_shading_language_100 extension
inside xgl (probably a mesa/nvidia thing).

So, in the spirit of Open Source, does anyone want to pick up the mantle?

Sorry to dissapoint those who want finished products!
