is an obscure website with very little public documentation on it. There
have been a few people who have tried to crack it
but I have no idea if the full
thing has been solved yet.
is fascinating to me. They have used exotic maths (or something) to
create many perfect number cubes as part of their puzzles (there were less than a
dozen previously known). They also release information
that they believe will
advance human society. Lots of stuff about them around the web, very interesting.

The Polish Plague Doctor
stego disc that circulated around some tech circles.
This is a particularly interesting excersize in steganography because of how many
pieces of data are hidden in a single file, the pieces of which are still being
figured out. Not to mention, it is strongly themed around the black plauge; spooky.
The Voynich Manuscript
was a linguistic oddity. Just recently there was a
that showed the text was written in ancient Turkic. It is still one
of the most famous cases of obscured texts. Here is a link to the full text
well as a transcription
of the symbols used.
The Copiale Cipher
was a manuscript from the 1700's for an ocult order and was
completely enciphered. It's a good example of an obfuscated historical text; a full
transcription of which can be found here
The Library of Babel
can be used to send messages, as technically everything is
already written in it
. There is also a similar function for images called Babelia
in which all images in the 640x416 dimension range theoretically already exist
Stego tools using similar functions are incredibly underutilized.
