Which way is this dancer revolving? Clockwise or anti-clockwise?




The Spinning Dancer, also known as the silhouette illusion, is a kinetic, bistable optical illusion resembling a pirouetting female dancer. The illusion, created in 2003 by web designer Nobuyuki Kayahara involves the apparent direction of motion of the figure. Some observers initially see the figure as spinning clockwise (viewed from above) and some counterclockwise. Additionally, some may see the figure suddenly spin in the opposite direction.

The illusion derives from the lack of visual cues for depth. For instance, as the dancer's arms move from viewer's left to right, it is possible to view her arms passing between her body and the viewer (that is, in the foreground of the picture, in which case she would be circling counterclockwise on her right foot) and it is also possible to view her arms as passing behind the dancer's body (that is, in the background of the picture, in which case she is seen circling clockwise on her left foot).

When she is facing to the left or to the right, her breasts and ponytail clearly define the direction she is facing, although there is ambiguity in which leg is which. However, as she moves away from facing to the left (or from facing to the right), the dancer can be seen facing in either of two directions. At first, these two directions are fairly close to each other (both left, say, but one facing slightly forward, the other facing slightly backward) but they become further away from each other until we reach a position where her ponytail and breasts are in line with the viewer (so that neither her breasts nor her ponytail are seen so readily). In this position, she could be facing either away from the viewer or towards the viewer, so that the two possible positions are 180 degrees apart.

If you look at her legs and blink a bunch of times you can make her change direction… from your perspective.

Nah I think that just means you’re psychotic or maybe it’s your one eye playing tricks on you.

It changes direction every time I look away and look at it again.

Yes! Me too.

Thank you for that. I thought I was the only one who was bonkers.
But I'm not, you are too!

I'm afraid so. I've learnt to live with it. 😄

At least I'm in good company. You've convinced me to embrace my bonkerness! bonkeritus?

Counter-clockwise.

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

No matter what I do, I can only see counterclockwise rotation.

Focus. When she faces you, she could also be looking away. The two legs overlap, which means the outstretched one can pass for both in front of or behind the other one.

This is one of those exercises of the power of suggestion. If I perceive something the correct way then someone comes along trying to change my perspective. She's spinning counter clockwise because she's facing towards us.

I've seen this on national geographic

Actually it doesn't

Well, this is a tomb. I'll make them feel at home

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

It doesn't what? Doesn't exist? Doesn't move in any direction? Doesn't look like Lara Croft?

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

The doubts!! It doesn't move, your brain is playing tricks on you

Well, this is a tomb. I'll make them feel at home

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

The same as ALL the gifs appear to be moving, but aren't.

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

Exactly

Why are her nipples erect?

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

She's spinning counter-clockwise.

Re: Which way is this dancer revolving? Clockwise or anti-clockwise?

Why are you calling it a she? Why can't a man have breasts?
