For reasons that probably only a good psycho-analyst can explain, I've spend considerable time of my life writing obfuscated code. I have two favourites in particular that you'll see below:
Calculating PI to an arbitrary number of digits
Inspired by the original in Intercal, I've written programs that calculate PI to an arbitrary number of digits in C#, C/C++, Java, Objective-C and Python . And since I have planned to learn Haskell in 2014, expect a Haskell version of that any time soon :)
But wait, there is more
Spread throughout the depths of this website you'll find more fine examples of my interpretation of programming best-practices
- There is a whole page dedicated to obfuscating Python
- There is an important advance in theoretical computer science: the Java Computed-GOTOs HOWTO
And a couple of more things, but finding those is left as an exercise for the reader...
