Writing a little application which takes two words of equal length and prints the valid words path from one the other is a great exercise. Staring with the first word, change one letter at a time, so as to end up with a valid word in the language of choice, until you have the other word. Try turning "comic" into "flair". This is difficult for a human to do. So do doing it code is interesting and revealing.
