Cool illusion. At the first glance, she is spinning clockwise (or otherwise), but then, you can change her direction. Here are some tips on how to do it: - You have to look down at the shadow, keep your eyes there for some seconds and then slowly move your eyes upward.
- Sometimes my brain even changes the direction when I look at different parts of the figure. Dont stare at her, keep your eyes moving up and down.
- when she turns clockwise she has the right foot up.. when counter-clockwise its the left foot.. just tell yourself which foot is up and she will turn in that direction.
Any explanations?
This is MY theory:
ReplyDeleteIt’s just a shadow. You can’t really tell if the image is facing forward or backward, but since we are used to people looking at us, our first impression is that the dancer is looking at us. The dancer’s leg is moving left, stops, right, stops etc. If on the split-second your eyes saw the image, the dancer’s leg was moving left - you would think that she was spinning clockwise. If it was moving right - you would think that she was spinning counter-clockwise. From that point, your brain had already decided which direction the dancer was spinning and it would be very difficult to change your mind without looking away. It is about the exact split-second your eyes first saw the image.
How’s my theory?
