Once you look at both forms, once it goes back to negative form, look at the dot without blinking or lookng away. Now...... stare at the B/W image. Experement with it.

^That type of optical illusion is my favourite. I can never get over how realistic the image looks in colour.

I'm sure most people have seen these, but they're my other two favourites:

A and B are the same colour.

Can see her spinning in either direction.

I dont get this one. When she is looking in our direction she is going left, and when she is looking forward, she is going right.

Look back, and you'll see it.

Yes but she can look to be spinning clockwise or counter-clockwise (from a birds-eye view). While she seems to be facing away from you, you can cause a shift in your perception so that she's facing toward you. This works for any spinning silouhette.

Focus on her outstretched leg and pretend it's passing in front of her vertical one when it's actually passing behind.

Now I am hopelessly lost
:panic:

You could do the same thing with that smiley if it were made into a silhouette.
Here, this should help, although it's a little confusing:

what is this i don't even

The spinning woman shows you what side of your brain is the dominant side.

Have you seen the Hollow Mask Illusion? Your brain tricks you, because it can only perceive a convex-shaped face, even when the face is concave.

Oh now I understand. its so weird, when you cover one of them up, the girl goes in another direction, and it looks like the gif is changing, when really it isn't.

Mind.... Fuck!

The dancing lady is really a great demonstration that your consciousness is not, as we commonly imagine it to be, just a passive mirror of the real world. In reality, everything we see is loaded with contextual interpretation. Particularly interesting to cognitive science is the fact that you can only perceive one interpretation at once, which seems like it implies a lot about the singularity of attention. The Necker Cube was the first demonstration of this. This is a rotating one. You can make it flip relatively easy by focusing on the four vertices on the left or the four vertices on the right.

The colour thing further demonstrates that we do not see reality as it is in an unfiltered form, but rather as it is useful to represent it. In fact the visual information that enters your brain from your eye is really rather a muddy mess. The brain just tries its best to hide this and build up a singular picture of the world. These two are really fucking unbelievable, in the literal sense:

The orange and brown squares in the middles of the two faces are actually the same colour.

The blue tiles on the top of the left cube are the same colour as the yellow tiles on the top of the right cube. Check it in Paint or something.

Why have I never seen those ones before? Even though I've seen similar illusions I didn't believe it until testing it.

Count the black dots.

I honestly thought that was going to be a screamer or something. Anyway, I tried looking at just a small part to see of the thing was a trick, but unless you follow the directions you don't see the colors.
