Non-alphanumeric Javascript?

Ever heard about Brainfuck? It is an esoteric programming language (designed with only one purpose -- to test the boundaries of computer programming... and human brain) that uses only eight single characters ([, ], <, >, +, -, . and ,) as entire set of programming words. Yes, it really fucks your brain!

To my (and probably to many other) surprise with proper tools you can turn regular Javascript into very similar brainfucking experience!

The idea of this article comes from Patricio Palladino's blog and is also explained in hisanother article.

To not waste your good joy of reading these text, let me only tell you, that you can "convert" for example this:

alert('Hello World!');

into this monster:
