I've seen it before, it's very cool. Incredible how your brain can be fooled, no?

 

Try forcing yourself to actually see the truth.

It takes almost a minute until I manage to adjust to it and even then it's immediately slipping away once I loose concentration

Very Cool..

I was an art teacher, and I used to bring stuff like this all the time to my students.. Kids see things adults miss.. and it was cool seeing and hearing their reactions..

The human eye and mind are amazing. They work to balance and counter balance each other. So much happens that we don't even know it is going on. We use color in ways we don't even realize...

 

SI

The mind searches for meaning and fills in gaps.

 

For instance, if you intentionally misspell and transpose the spelling of every word in a sentence, the mind can fill in the gaps and reconstruct a sentence due to knowing/guessing the context.

Have a look at these rotating snakes. It even works when you print it on a sheet of paper (just to ensure that it isn't some clever animated GIF)

Thanks for the suggestion. Originally I had to compare colors in a graphics program to convince myself, but now I can see it with my own eyes. It was tough at first, but it's getting easier. You can stop regarding A as a square and think of a parallelogram. Then sharply focus on A and ignore the overall picutre. Then shapes with the same color as A will stand out.

 

Have a look at these rotating snakes.

Thanks Chris, there a lot of cool illusions out there, more advanced than the ones from our childhood. "Best ever" was a bit of hyperbole. Another favorite I found just today is this dragon. It reminds me of a detail from Eternal Darkness.

The rotating snakes are indeed cool.

 

The principle behind the dragon is also how some stuff at Disney's Haunted Mansion is done. (The print-out version of the dragon doesn't work as well as the video suggests - it requires pretty even room lighting to work right.)

 

Edit: Okay, now the dragon works really well. Keeping it out of strong light helps, but the real key is to look away from it for awhile, then back again. My problem was that after having assembled it, I kept looking at it waiting for it to work, and my brain wouldn't "let go" of reality.

Those were okay, as far as optical illusions go, but check these out.

Nice! I wish my printer weren't broken. The instructions suggest looking with one eye as well, and that would explain why the video looks so good. Did you try that?

 

p.s. I've seen the sidewalk art photos before, and I agree they are cool.

Yep, but looking away for a minute worked best. If my brain sees it wrong (or rather, as it really is), it doesn't matter if I close one eye or not. I have to reset my vision by looking at something else.

Did you have one eye closed? It only really works with stereo vision toggled off. That's why it works so well on video... I think Disney's must work better even with stereo vision enabled because the shapes are rounded and almost completely white ("marble busts"), so your brain can't compare any edges between the two views your eyeballs provide.
