Obfuscated code contest winner?

[Moohasha]

I'm trying to find some source code that I'm pretty sure won the IOCCC (International Obfuscated C Code Competition). If I remember correctly, the code solved some sort of equation (I want to say parametric?), but if you fed the source code into the program as input, it rewrote itself as another equation solver that could subsequently rewrite the rewritten source code back into the original. If anyone has any idea what I'm talking about and where to find it, I'd be much obliged.

Thank you! That is one amazing piece of code.
