Scytale

Here we have the staff (a hanbo) and the ribbon.


Here is the ribbon on the staff. I used tape but anything would work. A tack, a rock, a split in the wood. Whatever.

w00t Atlantia!

Now I've unwound the ribbon. Kinda hard to see what's there, isn't it?

Rewrapping. Notice that even wrapping it differently can make the message unreadable.

Wizardry!

Now I've wrapped the same ribbon on a slightly larger staff (maybe a 1/4" difference) and the message is illegible.



Just a pile of ribbon, or a declaration of allegiance? BOTH!
