It's now reasonably well-known that the book's strange page-numbering system has been cracked (it's a funny kind of base-21 counting, with various unlucky numbers removed), but the text itself remains enigmatic. Ivan Derzhanski has posted some observations here, but I think it's fair to say nobody yet has the foggiest idea how to go about trying to read it. Oh well!
Incidentally, there's even a ballet based on it!
