	Hi, Claus and Nick!  I like this idea for its
novelty.  The turning grille cipher is a classic
regular transposition cipher; see Helen Fouché Gaines'
*Cryptanalysis*.  However, I've never seen this sort of
application of it.  

	As Gabriel asked, how does it look for our other
statistical tests, such as the Zipf's Laws?  

	Also, Claus filled in 80% of the spaces with plaintext
and the remaining 20% with nulls.  The 80/20 split is
just what we see with Robert Firth's paradigm; about
80% of Voynitext follows the 24th of Firth paradigm:

About 55-60% of Voynitext fits the Tiltman paradigm, to
be found in D'Imperio's book and at 

http://voynich.nu/list.html#quan   .  

Does the 80% of the text filled in through the turning
grille's spaces fit a paradigm such as Firth's?
