How would I go about posting an animated .gif?

You can post them, but they have to be pretty small file sizes. Most animated GIFs are too big.

Is this one of those magic eyes, or is there another trick.

I can't do the magic eye things. I guess my eyes aren't magicamal.

glatt 12-05-2011 09:44 AM

Look at 7 o'clock in the image. You'll see the face. No trick. It's just a where's Waldo type thing.

infinite monkey 12-05-2011 09:45 AM

Oh! Hahahhaa. That's kind of creepy!

Now I see where's he's bean.

classicman 12-05-2011 10:26 AM

glatt! you gave it away! :(

infinite monkey 12-05-2011 10:29 AM

It's been 3 days. I think the statute of limitations was up. In other words, I don't see anyone clamoring to solve it. ;)

classicman 12-05-2011 10:46 AM

well poo on you

infinite monkey 12-05-2011 10:47 AM

LOL

I was squinting and leaning back and everything, thinking it was a magic eye picture.

classicman 12-05-2011 10:51 AM

Doh - I just realized what you meant by "magic eye picture."

Sorry! I figured that anyone who wanted to play the game and look for it would look for it. They wouldn't scroll down hoping for an answer.

classicman 12-05-2011 11:44 AM

no worries.

Sundae 12-05-2011 12:16 PM

I have to admit I saw it immediately.
Not boasting, that's the way it is sometimes.

Although I do have a vague memory of seeing it before, which would have helped enormously.

Nope.
This one I don't get at all :)

BigV 12-05-2011 08:56 PM

it doesn't appear to you that the woman's standing on a floating / flying platform with the shadow cruising along underneath? That's what I see.

Sundae 12-06-2011 08:20 AM

It does now!

classicman 12-09-2011 11:54 AM

Explanation from the Doctor ...

Quote:

Perception is not reality - it is perception. Reality remains reality and our perception simply attempts to represent it, but fails to do so accurately. In this case our eyes (ie retina) receive the actual image perfectly. Photoreceptors have overlapping fields of vision and these overlapping fields of raw data (i see light) travel through several levels of "processing" (ie perception). This starts in the ganglia within the retina and continues and is completed in the visual cortex and occipital lobes. For a variety of reasons this processing may actually distort the reality as is seen here. Sometimes it is merely a physiologic limitation, sometimes our brain is attempting to accomplish another goal other than the pure representation of reality and we get the situation we see here. I believe the presence of perfect squares arranged into perfect circles is the problem - our brain "wants" those squares to travel in a linear fashion, but they don't, and it creates a perceptual tension. It would be interesting to see if the phenomenon is eliminated by using small circles rather than squares

Not so much an optical illusion, but, it makes ya look twice...

Love the zebra shadows.

Infimonki's picture has an effect on us similar to when a person goes on TV with a shirt with thin contrasting stripes. The cameras are usually good at accurately representing what is in front of them, but certain patterns hit the hardware in just the wrong way and produce strobing effects. Likewise, our usually (moderately) accurate sensors aren't ready to cope with inputs like that.

I suspect the angles of the squares is critical, because they trick the brain into thinking the circle at that point is aligned with the edge of the squares, which makes us project the circle in the wrong direction, causing the circles to look overlapping and entangled.

Wow - you said that SO much better than I ... Gonna send that to him.

infinite monkey 12-10-2011 06:29 PM

I think my brain asploded.

I like the zebras too, made it my background.

My wife is making Xmas cards, so I asked her if she could incorporate this in some of them:

http://upload.wikimedia.org/wikipedi...lusion.svg.png

If you look at it for a few seconds you'll think that there are blinking lights at the corners of the squares.

I'm trying to find something similar in color that can be made to look like a tree.

the lines are a little too fat, but something like this?

HungLikeJesus 12-11-2011 11:18 AM

Yes, like that, except I can't see the blinking dots in the color version.

footfootfoot 12-11-2011 11:59 AM

That's partially a function of the lines being too thick and also somewhat the contrast in value. Yellow and purple may work better. Lemme see.

This is a bit better. There is a red/green combo in pigment that is particularly electric. I don't think it works as well with monitors. Though maybe it's and RGB vs CMYK thing. It could also be that the pigments themselves have an intensity that can't be mixed with CMYK

Sometimes the answer is a simple one:

I think the scintillating grid actually has lighter colored dots at the intersections, which give the blinking light effect.

infinite monkey 12-11-2011 03:34 PM

I saw blinkies on both of the color ones too. Made me seasick. I see them as soon as I look at it too. They're fainter on the color ones, but I see 'em.

HungLikeJesus 12-11-2011 04:03 PM

Well, those are supposed to work better when you view them from farther away, and you're way out in Ohio.

infinite monkey 12-11-2011 04:55 PM

Yeah, plus I'm drunk.

I'm kidding. I kid.

Yeah I started dicking with making brighter dots and then was all like, fuck it I'm going to go take a nap and not clean the kitchen.

Looks like a leaping Great White. It ain't. It was shot from beneath, near the surface.

Kinda illusiony.

Attachment 35857

classicman 12-12-2011 04:58 PM

Doesn't look like a Great White, jus sayin.

ETA - Maybe it is - I thought at first it was a Black Tipped, but some images show Great Whites with similar markings (shrug)



Dolphin!

I'll go with black tip reef shark, per Classic, and Wikipedia.

It's all part of the illusion.

Elspode 12-12-2011 09:44 PM

I can't believe that no one has said "It's a dolphin"...until now.

So what's with the baby shark? No one seems to care about the baby shark. Is it a baby shark? It looks like a baby shark to me.

Think of the children. :(

classicman 12-13-2011 01:15 PM

Are you talking bout the remora?

infinite monkey 12-13-2011 01:18 PM

I don't know. What's a remora?

(Whatsa remora with you? Ba Dum Dum)

Looks like either a baby shark or a tattoo of a baby shark, on the bottom of the shark.

infinite monkey 12-13-2011 01:19 PM

ohhh, I googled it.

Never heard of it before, I guess that's what it is!

Scriveyn 12-13-2011 01:31 PM

It would have to be a tiny white, judging by the size of the suckerfish (aka remora or sharksucker).

ETA: oops, I see I was late

infinite monkey 12-13-2011 01:34 PM

Suckerfish get that big?

OMFG, quit making such a big deal about it, you.

Not you, Scrive. ;)

IIRC, there are some that try to "attach" themselves to scuba divers.
There is probably a video somewhere, but I'd be making a BIG DEAL about it so I won't look for one. :3_eyes:

infinite monkey 12-15-2011 03:20 PM

If you leaf me now
You'll take away the biggest part of me...
Oooh oooh oooh oooh no baby please don't go

Sundae 12-15-2011 03:26 PM

Approx 5 seconds.
Again, not boasting - I have my own problems...

We had the afternoon performance of the Nativity on Monday.
One of the Innkeepers was playing up all the way through - headress on, headress off, whispering to the children next to her, fussing about the children sat in front of her, turning round and trying to fiddle with the wall behind her when she should have been singing etc, etc.

She was too far away for me to get her attention. I assumed she was in the class above ours. So I spoke to Mrs N at the "briefing" the morning after (the children still had an evening performance to do).

"Little girl with glasses at the back."
Nope, no one there with glasses.
Whaa?
Oh and then T slips in.
T is in MY class.
All it took was a headdress (like one for a shepherd) for me not to recognise her.

Damn. Had I known she was one of mine I'd have had a quiet word. As it was, she was mentioned as behaving badly in front of the whole cast.
