Almost always works for me.

[edit]
The cat is easier to switch. Once you realize the illusion is in that the cat is actually spinning at all, you imagine it going the opposite way when it's facing "backwards" and since there are less frames it switches more easily.

The face one makes sense how it works. The finer detail is visible only from close up, but the shadow and lighting detail becomes apparent as the finer detail is lost due to distance. It looks like they took two pictures of two different expressions, took them in photoshop, made a high pass filter of both and copied and pasted the opposite face and overlayed them onto each other, while mildly blurring the original background image. That one makes much more sense than the spinning cat and woman imo.

That's what I get for just looking at illusion and not reading the post--didn't realize the face one was already explained.

Wow - great tips!

Of course I couldn't stare at it for more than a second before the light felt too bright and I kept scrolling down. Then I realized way embarrassingly late - that was it! Bright light can't emit from a computer screen.
It even seems to be emitted by plain paper - first I thought, it was too simple to post it - but itīs funny, how you can almost not trick yourself out of the avoidance of stuff that gives you blinding sensations.
It does take a while of looking at it to realize this.


One more:



Not really something nobody saw before - but stunning non the less I find - and you donīt have to look it up - I can directly post the thing.

Watch the X in the middle very closely. You should start to see a green dot that rotates around the circle - this dot is an illusion; then you should see see the purple dots disappear.... but they haven't really gone. It is an after image effect, sometimes called a 'negative retinal afterimage' - move your head slightly, and the dots will reappear...
