Hi all,

while steganography is not new and is often used to hide stuff inside
images or videos, i thought why not give a 3D model file a try.

So i took an old little .3dm file of mine and embedded an .mp3 file
which i created with macOS's say command and then run through
the lame encoder.

Maybe some of you find this interesting for inserting a hidden
copyright notice etc. in your files.

Please note: I did not extensive tests, so in case of any (file) damages
i am not responsible! It is more or less a test for me, if this could be
done.

Here is a picture of the model:



Here is the link to the .3dm file (expires in 30 days):

and here is the link to the software i have used. In the binaries
folder you can find compiled versions for most platforms.
