Wow! I just joined Facebook, and I've already got eight completely fictional friends! To see their names (in alphabetical order), find the extraneous letter in each Down clue (which must be removed before solving), and read these letters in clue order.
Or you could just look on their individual walls. That is, certain Across answers are too long for their spaces, and you therefore must write one letter in each such answer on the "wall" between the squares occupied by its neighboring letters. The letters on the walls are just my friends' names, after a certain transformation.
Anyway, I hope they're not mad that I put up a goofy picture involving all of them! To see the picture, take each Across answer not used above, and apply the transformation you found. Then for each letter sequence that results, go from wall to wall as described to form a small drawing; all of these together form the complete picture — one that a lot of people would consider so embarrassing!
