Mine is not working out well, even though I RECRUITED people to help me go over it.
My idea was this: Start at x, of course.
Now we have A H R M M T Y D in the source. So we start at x, and connect x to the different letters (in order, the problem with this is that there are still many possible routes to go) and record the letter of the direction we went to get there. Nothing I have so far really makes any sense. Another problem is the two m's...they don't connect well. A is also the only vowel you can use this way.
