Just found this animation in my mailbox which was submitted by one of our fans – Brad Snyder. I’m not exactly sure how it functions, but the illusion should be similar with our famous Spinning Girl illusion. Apparently the gem we see below is rotating in only one direction. Because it is shallow, it gives you impression it changes direction every few seconds. Don’t take me for granted, though. I have a feeling I don’t get this illusion in its full sense. I would appreciate if some of you managed to understand it, and post a clue for me and others via comments section. If my intuition is right, this can easily be one of the greatest illusions on this site. If I was wrong, don’t hate me…

i could be very wrong, but from looking at it it seems like the top and bottom turn in the same direction for some time, but then at one point, the top or bottom stops spinning and the other part continues, creating the illusion that its spinning in reverse
maybe?
well either way its a pretty awesome illusion
:D
FREAKIN SWEET
Pish-posh, I’ve seen much more complicated illusions in my lifetime. This one is very simple. The top of the diamond spins half the time the opposite way then the body of the jewl. Case closed.
If you stare at the bottom/point, it always appears to be in the same direction.
The top is what gives the illusion. If you cover up the top with your hand then the bottom will just keep going in the same direction.
Maybe I’m stupid, but its only spinning one direction…
That was pretty awesome :D Could have been more exiting colors thought.
PS: You should set someone else in charge for the magic site… If you are in trouble of finding one I guess I might be able to run it, atleast better than your brother (Don’t take that bad)
not bad. by far the best animated illusion on the website. well done.
Lame. The bottom continues in one direction and the top switched back and forth. Easy to see. I don’t get the fascination.
the trick is rather simple. It relies on retinal disparity in the shading of the lighter hexagonal “top” and darker triangular “bottom”. This first creates a three dimensional appearance, which is then confused with the movement.
When the top and bottom are in alignment (spinning the same direction) our brain appropriates this to mean that the object is solid.
However, when the top section reverses rotation, yet stays in the fore layer of the image, the lighter overall shading still makes it seem to be in front, as a 3D image. The reversed rotation of the bottom section separates it from physical attachment to the top and we therefore perceive the object to be hollow.
Does that make sense?
If you keep your eyes on the pointed end of the cone, you’ll see that it rotates in only one direction.
This is a tricky one, but its basically the same as the rotating girl one.
The upper part ist the part that makes the brain switch directions, BUT if you cover it with a hand or omething you can also make the lower part turn in either way.
If you now slowly take away the cover you can take control of the entire strukture.
Once you get the knack, you can have it turn in the direction of your choice ;) (so as said before it’s basically the same as the rotating lady dancer)
It is rotating in one direction. look at the tip on the bottom. It rotates clockwise. Hope this helps.
i agree w/ kevin… when the triangles “match up” it turns “hollow”
This is cool!! I like it!!
If u just watch the bottom of it the whole time, u can see how it’s moving in only one direction. It messes up ur mind if u watch the top. it’s REALLY COOL!!
It has no sense in reality …. is an image in three dimensions that when the top is in a position in which it should be behind the body appears forward… nothing else….
For all of you ppl who are saying this illusion is silly or not good: shut up and go home!if you think it’s that bad why don’t you make your own illusions site!
btw Draikyn, i read your comment like 5 times and still dont get a thing :D
THIS IS AWSMOME!! the point of it is when you watch it for a while it changes rotation the other way and back again!
I think its like this..The Gem is supposedly spinning in one direction but if u notice closely, due to the shadow, the gem is spinning only half direction..Half way clockwise, halfway anti-clockwise..
THE GEM APPEARS TO CHANGE DIRECTION BECAUSE MOST OF THE FACES ARE ‘TRANSPARENT.’
ONLY THE TOP FACE IS NOT CLEAR- THE PATTERN ON IT SHOWS THAT IT IS OPAQUE, AND THIS FOOLS US INTO THINKING THE REST OF THE FACES ARE TOO.
THEY’RE NOT!!!
IF YOU STOP SEEING THE FACES AS SOLID AND OPAQUE, THE GEM WILL NO LONGER FOOL YOU.
So just imagine the gem is made of glass- so you are always either looking AT the top face directly, or you are seeing it THROUGH the other facets.
And one more thing- THE GEM IS ACTUALLY SPINNING ANTI-CLOCKWISE. IT DOES NOT WORK THE OTHER WAY.
hope that helped…
Some people did have similar ideas before me, so, well, sorry to those people.
Normally I’m one of the people who whinges when someone says what was already said…
so again, sorry.
This is spinning in one direction. One side of the spinning object is transparent and allows you to see the top from the underside. When the transparent side is visible this makes the object seem to change direction, but it does not. Cover the top portion of the object with your hand and focus on the bottom point and you will see that there is no change in rotational direction. :)
If you watch the bottom tip of it(the point) it won’t look like it’s changing direction.
If you concentrate on the sides and not the top, you can see that it does actually only rotate in one direction but a slight distraction and even then it appears to be rotating the other way.
Very cool illusion.
you have to look at it from the inside and only look at the top from underneath…as soon as you look at the top of the gem from the top it seems to change direction…concentrate because as soon as you lose it it appears to be changing directions.
I think it was amazing and didnt get it at first, but think I understand now!!!
this is driving me CRAZY!!!!
Very cool!
I scrolled my browser window so that I could see only the bottom, and then only the top, to see if it really was spinning in just one direction…
Obviously, yes, it really is. But it was neat seeing it that way.
I’m not sure I fully get it… But then again, it’s late and I should be finishing some projects and not looking at 3D diamond optical illusions but you know how it is…
there are two separate rotations, one is visible from the point at the bottom, the other you will notice if you watch one of the top points of the object.
duurrrrr it goes see through whiles it is spinnin that was easy
get a life people
me,tom,jack ‘n’ tom
waz ere 2ka
in da ouse 09 !!!!!!!
it goes see through whiles its spinnin that waz easy get,a life people lol
me,tom.jack ‘n’ tom waz ere 2k8 in da ouse !!!!!!!
this is awesome! ive also seen this type of illusion with a dancing figure of a woman
The bottom tip of the jewel is making a 360 degree circle giving the illusion that the direction is changing when it rotates toward the back although its not….pretty cool
look at the video it makes it more understanding
It all depends on which side of your brain is dominant, because it is spinning on both direcions, some people see it spinning right, others, left. Some people see it go backwards and forwards because they are paying too much attention to unnecesary detail
the illusion is that goes from solid to transparent
Im not sure what the illusion is supposed to be.
Was the initial design supposed to be solid or “hollow”?
Look at it one way and u see through to the backside the entire time. The “field of view” being inside the object. (it spins one way)
Look another way its solid and it looks like the top switches directions. (which ruins the illusion of it being a solid object)
So the question is, which way is meant to be the illusion or how was the “illusion” created?
I think the answer is its not supposed to be “solid” and is simply a case of the “fov” being inside the object. Is that supposed to be an illusion?
We this in my science class it has to do with what side of your brain your using.
