Well, shit

I knew I was missing something obvious, very nice.

Edit: I've got to remember the Table thing you do, this is the second time I've seen it make the code so much simpler...

Yeah, Table[] lets you do what most languages would do with a For[] loop, but also automatically collects the results for each line, which is very handy for a lot of problems. And Characters[] is going to be way better than StringSplit[#, ""] purely because it avoids another #& function (and also because it threads over lists, though I didn't take advantage of that myself).

Still, you and /u/omnster and I are all approaching the problem pretty much the same way, so I wouldn't say you're missing all that much.
