Yeah, that would be problematic.  If L is the number of characters,
then the search space is 2 ** (L - 2) [see reason below].  So with a
33-character word, 2 ** 31 is 2.1 billion.  That might take a while in
Ruby 1.8.6.  But in 1.9 ....  ;)

P.S. The second character always follows the first character to the
right.  Each subsequent character could continue in the same direction
as the previous direction or make a right turn.
