Welcome back!

As I have told in my previous post on The Right Brain vs The Left Brain Test - The Spinning Dancer, there is no trickery used - the fact remains that the image is a constant 34-frame loop representing a full revolution of a dancer, and the effect in which the viewer perceives the dancer to be revolving clockwise or counter-clock wise is entirely caused by the ambiguous frames where the spinning dancer’s legs and arms cross over each other.

However, it seems many people are finding it difficult to see the dancer turning clockwise and counter-clockwise.

So, here are the two animated images which clearly shows it turning clockwise (on the left GIF image) and counter-clockwise (on the right GIF image).

The only difference that these images are from the previous Spinning Dancer image is: This one has the legs marked as “L” and “R” which clears such ambiguous perception for a more clearer view.

    This is an excellent illustration of our eye/mind playing tricks with us. To me both seem like synchronized dancers, either they both spin clockwise or they both spin counter clockwise.

    I am with Ivs, they both appear to be spinning in the same direction to me.

    I’m clearing seeing the left one moving clockwise and the right one moving anti-clockwise. You must be looking at both images at once, hence making your brain more difficult to interpret the rotation. Just try to concentrate on one image with “L” marked on the leg and you’ll find it moves clockwise.

    At first glance I saw them moving on the same direction until I opened 10 tabs for ec dropping which made loading the window slow and made the dancer move gently, I can see clearly the first image is moving clockwise while the other is moving counter clockwise.

    Wonderful illustration! Because I’m an animator, I was able to see the difference pretty quick … but not immediately. The difference is in the grey/white line down the pivoting leg. If you focus on that, it’s easier to distinguish left and right. Otherwise, the deceptions occurs because the silhouettes appear to be front or back, as they are void of back or front details. Thanx for the exercise.

    The toughest thing about success is that you’ve got to keep on being a success. Talent is only a starting point in this business. You’ve got to keep on working that talent. Someday I’ll reach for it and it won’t be there.

    This rises a very serious question of how many other sensory perceptions our brain may interpret alternatively.
    Each of us interprets the reality differently, through our individual brain-filtering proceses.
    What I say is not necessarily what you hear.
    What I see as RED, the colour blind see as gray.
    When I say that this is absolutely TRUE. You may see as false.

    We are all subject to optical and motion-illusions. But also to emotional, doctrinal and conceptual illusions.

    The moral of this story is that, even if one uses the best effort of critical judgement, one can never be sure to have grasped the reality.
    The Schroedinger’s Cat sort of quandary.
