How did you find this, who's behind it? It's genius but searching back from 'mauke polyglot' I can find nothing about it!
Sadly I can't give an answer; it was just in my list of interesting links that I'd saved. Google also seems far less useful now than it was for searching obscure things... or perhaps the source of that is a part of the Web that no longer exists.
Once saw a polyglot program used as both a build script and the program to build. It was part C++ and part batch script, though for the most part the C++ part just #included several cpp files.
