FWIW I made a Whitespace compiler for .NET as an exercise a few years ago. It works with Microsoft .NET and Mono, and emits compiled MSIL code.

Here's a list of languages in the same vein:

It's not brainfuck* though, is it?

aren't whitespace, brainfuck* and ook! the same languages (just differently named keywords)?

Amusing as this may be it's not very impressive, since it's easy to code any program in any language as sequences of whitespace and then simply decode before passing it to the translator or compiler.

My favourite example of which is perl's Acme::Bleach http://search.cpan.org/dist/Acme-Bleach/lib/Acme/Bleach.pm

The wars over source code formatting must be epic!

I can't wait for a printed book about this new language.

It's also interesting to note that you can select all text to "see" the whitespace code, although that only works for me in Firefox, not in Chrome.

no, you can't. you see the just the silhouette of the code, not the while code itself - because when selected, tabs and multiple spaces rougly look the same.
