Each letter contributes to a three-letter word: either up, down, left or right (no diagonals). Each combination of three letters makes a different word in at least one direction. I hope that makes sense... I can barely wrap my head around it myself! Not as awesome as it was in my mind, but I spent a long (long!) time getting a grid that works, I figured I'd release it. Note: a couple of words are obscure but valid. Good luck!
