Well, shit... now I must resist the urge to go back and figure it out! I've got things to do this weekend, couldn't you have lied and said it wasn't really a challenge! ;)
Yeah when I built that I was way too deep in the steganographic rabbit hole. Might have to rework it at some point, because it needs a deep understanding of how to use statistical analysis to find a key/alphabet, and the frames that don't match the previous audio frame so that the codec skips them as corrupt frames. It was the year after 3301 so well...I kind of overdid it :D
Maybe something assembly related would be fun to do, too. These days I am reversing lots of malware, so sth like patching a binary so that it evolves into a different program similar to how APE does it would be a fun challenge, I guess :D
