What Do You See?

I first saw it as a cube with a smaller cube cut out of an upper corner. And then, almost as easily, it looked like an upper corner of a room, with a small cube placed in it. The changing colors made it easier to switch between these perceptions.

One of my many failed efforts at considering Fermat's last theorem.Nice post, Tony, but I am now doomed to pondering that for several hours. I've no idea of the apt emoticon, so you can have several - .

Three parallelograms, inside a hexagon, inside a hexagon.

A colorful Necker cube!

A company logo without a company to accompany.

I certainly don't see an animation.

My wife is an artist who often carries a sketch book with her; she got a great kick out of this. She has done a few optical illusion paintings.

Be careful she doesn't paint you into a corner.

I'll get out of it by borrowing Tcmtech's alternative-universe wormhole.

I see the reason why three orthogonal views are required to properly describe an object that appears in an isometric drawing.

...said a blind man when he picked up a hammer and saw.

Or the deaf man who saw the shepherd and herd.

"Oh I see." said the blind man to the deaf mute.

Like previously noted, I first saw one version then the other.

This is a shape that was commonly used as a test for students to interpret in 1960's high school drafting classes. They were intended to show how difficult it can be to adequately describe a 3D object on a 2D media.

A rejected Rubik's Cube.....

A cube subtracted by a mini-cube on the corner fronting the eye view. Individual lights are illuminated at 3 sides, simultaneously and interchangeably. The other side on the perspective view is darkness.

Took a while, but now i can see the room with a cube in it that Tornado saw. I could at first only see the room when the left wall was blue and the right wall Red and the floor Yellow.

Petty cool, thanks.

A Rorschach test for Engineers?

A kaleidoscope of shapes of primary colours.

Hey!!!! It's 1968 again. I had a very similar poster on my dorm room wall. My trusty GE black light bulb, which still works, made that look awesome. Well, at least we thought so when we when In A Gadda Da Vida was blasting loud and we were a bit spaced out man.. I sat and drew variations on this back then.

Thanks for the "trip" down memory lane, or what I think I remember.

This image doesn't seem to change colors, but...................................

Thanks Lyn,

Now that I'm home, it shows up in the post. It must be something with my company's internet filtering.

It DOES change colors.

Welcome.

So it does. Guess I was in a hurry.
