@Linkat,
tsk...
ok, I get it, you're looking at the pictures like trying to interpret what the dots or waves or lines mean. I think I get what you mean when you say you saw roosters. You're looking at a bunch of, um, color lines sort of, that turn at the top, like you're seeing rooster combs.
And this pink on, you're looking at the darker rose colored area's and seeing what can be interpreted as a bunch of mouths....am I right?
No, you have to GAZE at the picture steadily, from 6 inches to a foot or so, after awhile, a 3D image starts to appear that looks nothing like the picture that you see superficially.
It's like you were gazing at a section of smooth sand, then someone comes and press their hand or foot into it, and now you can see the impression of a foot or hand. The contours, ridges, etc.

I remember years ago, hanging out at my SIL's house one Sunday, and she had bought one of those calendars with the magic pictures. My husband looked at one for awhile and said "whoa, now I see it." He told me "It's an African savannah, with giraffes and zebras standing around. Knowing him, I thought he was just jerking me around. We'd all taken turns looking at the pictures, and he was the first one to get it.
A friend of my SIL was there. My SIL was the only person in the entire world who could stand her. We used to call her Eva Braun (she was German, no offense to CJ, this woman was just freaking mean, controlling and awful) She'd been saying all along, "Zer is NO picture! Abzolutely NONE!"
I laid on the sofa and relaxed, and Wally said, "here, I'll help. when you do see it it, a zebra head will be here....and a giraffe head here....and legs here." then he left me alone to figure it out. After awhile, my eyes glazed over, then, all of a sudden, for just a second...I saw a zebra! I got excited and my eyes refocused, and I lost it. But then I knew more what to do, and in a little while I said "WOW, I see them all! 2 giraffes, 3 zebras, and a tree"
Eva Braun started going bezerk. "NO! Zer is NO pictures! You are just be-ink hoodvinked into zeeing zhis through the power of zuggestion! You are zhowing you are veak minded and eazily svayed!"
Awhile later, Eva had a couple of vodkas and was just starting on a third one, and she idly picked up the calendar and looked at a different page.
The rest of us were just talking, and she for once wasn't telling everyone what to do...after a bit she suddently sang out "MEIN GOTT! ZER IS A KID PLAYING HOPSCOTCH IN ZIS PICTURE!"
After that, she told us it was all about the powerz of perzeption.
