OK. Sorry to spam here but you know, no edits
The text string "RzRaVElNQlRHTVpUQU1aVEdNWVRHTkpUR1laRUtOWllHWVlUT01BPQ" is no longer in the source code, if it ever was (I don't doubt it was, I just didn't see it personally). That base64 decodes to G4ZTIMBTGMZTAMZTGMYTGNJTGYZEKNZYGYYTOMA= which looks like it should decode again, but I can't get anything out of it, and I wonder if we were supposed to see it even given it's not there now.
Likewise, the cached version from google that links to the bandcamp has 62636A68206364776E6D in a comment in the source code, which is ascii "bcjh cdwnm", guess what, rot17 encoded again, "stay tuned". Which, uh-huh. (I didn't go in on that cached page before in case this was a Twoism recs thing, cos it felt like we weren't supposed to have seen that but if you pinkie swear it's not you behind this, Mexi
)
No idea on the matrix of 9 three digit numbers in that graphic on the last page, except it seems odd that it's counting down 987 654 32 if you read them column wise... think that's used up my GCHQ-fu for the day.
