Typeface Mechanics: 001

Typeface Mechanics: 001 | The brain and illusions | Scoop.it

Our conscious minds want to draw one shape, but our eyes need to see another. Part of typeface design is managing this eternal friction between logic and optics. It’s always there, no matter the style.

Gerald Carey's insight:

A very interesting article on the fight between logic and illusion in the world of the typeface.

Interesting take down of the above 'spiral'.

Mindbending Optical Illusion Tattoo Adds A Handle To This Guy's Arm

Mindbending Optical Illusion Tattoo Adds A Handle To This Guy's Arm | The brain and illusions | Scoop.it
Some optical illusions are even more impressive in tattoo form, where they radically change the appearance of the bearer's skin and, for an instant, make us question reality. It almost looks like you could grab the swirling column tattooed on this fellow's arm.
Gerald Carey's insight:

Impressive...for a tattoo!

Floating Sphere Optical Illusion

Floating Sphere Optical Illusion | The brain and illusions | Scoop.it

Scrolling this image up and down, or moving your head simultaneously while observing the sphere produces an interesting optical illusion effect – a floating movement of the central object.

Gerald Carey's insight:

I don't usually post a lot from Mighty Optical Illusions because that's all they do - post optical illusions. But this is a good one which becomes even more illusory if you move your head from side to side.

The Power of Perception: Why You Can't Unsee These Images | The brain and illusions | Scoop.it
We're going to rewire your brain. Are you ready?
Gerald Carey's insight:

The image above is an example of the content of this excellent article on 'unseeing' images once the details have been explained to you. It's much like aural pareidolia - you don't hear the pattern until someone points it out to you and then you can't "unhear" it!

This is a great article about this concept with some new images (and plenty of old ones) clearly showing this concept.

You Must See These Sidewalk Chalk Art Illusions

You Must See These Sidewalk Chalk Art Illusions | The brain and illusions | Scoop.it
For most people, a sidewalk is a convenient way to get from here to there and the best use for an asphalt parking lot is to park your automobile. For a sidewalk chalk artist, these surfaces are viewed in a completely different light. They represent blank canvases awaiting temporary masterpieces to be drawn onto them.…
Gerald Carey's insight:

These chalk drawings (what an understatement) are becoming incredibly complex pieces of art. Magnificent.

Don't underestimate your mind's eye: Objects don't need to be seen to impact decision-making | The brain and illusions | Scoop.it
Objects in our visual environment needn't be seen in order to impact decision making, according to new research. Take a look around, and what do you see? Much more than you think you do, thanks to your finely tuned mind's eye, which processes images without your even knowing.

Not sure about this study but the picture above was interesting. When I first looked at, I couldn't see any pattern. When I read that it was two halves of a maple leaf, I instantly saw it!
