A while ago I put together http://twoletterscrabblewords.com/ to visualize the two letter pairs that were possible. If you click on any of the tiles you'll see the valid pairs, unless the tile is grey, in which case there are no pairs for it.
I was hoping that it would be useful as a study tool for people who are more visually inclined - I wouldn't have considered using mnemonics originally.
