... Fibonacci numbers. Is that deliberate?

Wow, very perceptive, jdalbec! The use of Fibonacci numbers is not coincidental; it's a sort of signature that I use in a lot of my obfuscated code. I meant for it to be a hidden element, but there you go finding it as the first replier!

I (foolishy) started all this nonsense after posting my first obfuscation, Fibonacci, before becoming a member. The use of Fibonacci numbers in this particular obfuscation is (in all honesty) quite silly.
