Deeply disturbing, grotesque, perverted and vile

[DeeBye]

After the first couple I figured out what to look for.  The logic is actually very simple so you don't have to memorize the sequence.

I assumed that everyone knew it was a "one of these things is not like the other" puzzle :huh:

It seemed clear to me after the second iteration.

That being said, the toughest part of that puzzle is the fact that it carried on for like 20 iterations. I got most of them right quick, but a few of them stumped me to the point that I was doing random clicking.
