This isn't so much an obfuscation as an obfuscation of an interpreter for an obfuscated program in an obfuscated language (the aptly name brainf**k, which can be read about here). Thank god for eval.

As a sidenote, i'm only using 7 of the 8 available instructions, though the interpreter can also handle the eighth. Can anyone spot what it is...
