Obfuscator & compressor for JS, HTML & CSS

Compressors for web documents are all over the net. The idea behind them is simple: strip whatever is not used from the file (like spaces, comments) and thus make it smaller (which results in faster loading times and less bandwidth consumption).
However, I haven’t came across a good open-source web obfuscator.
Wait, what’s an obfuscator?
Obfuscators transform human-readable code into hard-to-understand code. Programmers use them for various reasons, like concealing its purpose, to deter reverse engineering or just to create a fun challenge for other programmers.
Meet Patu Digua
Adrian Ber, a friend of mine (and great programmer) has created a tool (written in Java) that does both compressing and obfuscation of web documents.
It supports Javascript documents, HTML pages and CSS stylesheets.
The tool is named after the smallest know spider in the world – pretty suggestive
Patu Digua can be used from the command line interface, in your Java program or from the graphical interface (in Windows).

Patu Digua is open-source, so if you want to see how it works or get involved in the project, you can do so on its homepage.
