It seems so close... | Comment 11 of 18 |

With the thought of casting nines in mind, I decided to keep on adding numbers one at a time in mod 9, and every time I reached or passed 0 mod 9, I highlighted the number that I had just added.

For example, the first row (everything is in mod 9):
5+7 = 3, highlight 7
3+2 = 5
5+4 = 0, highlight 4
0+9 = 0, highlight 9
...

I actually tried mod 10 at first, and didn't get any results.  I also tried carrying over the sums from each row to the next (for example, the total sum of the second row was 1, and I tried starting at 1 for the next row).  I got the best results in mod 9, resetting the sum each row.  This is what I got:

 x xxxx   x   x xx xx x
x x xx x x x x x x xx
x xxx x x x x x x
x x x x x x xx xxx
x x xx xx x xx xx x


I got excited when an I, an R, and an O appeared, but the last two letters seem to be messed up, and the RO isn't exactly perfect either.

  

Three possibilities:
I added incorrectly, since I did it by hand.
My method is almost correct, but slightly inaccurate.
I'm on a completely wrong path, and this is just a coincidence.

My guess is that the word is IRONY.  I love irony.  Is that so odd?
