desperance said that she was going one direction for him, but then as he read a list, she reversed to the opposite direction.
For me she started out clockwise with her right foot up. Then I looked around the page, but nothing changed. Then I read the first list (left side) and nothing changed, second list (right side), nothing. Then I slightly unfocused on the first list and she switched to be going anticlockwise with her left foot up. Then I glanced unfocused at the second list and she reveresed again to clockwise, right foot up.
Now, just looking at the first item on each list is enough to get her to switch directions and change feet. From my perspective (of not knowing how this works at all), it appears that the pressure of my eyeballs on the part of the screen where the lists are located is what is changing her direction and foot.
So, what I want to know is: (1) how is this illusion constructed so that the switch is available to occur? (2) why does just registering on each list act as enough of a trigger that my perception flips her direction? (3) why does this illusion occur - what real life thing does this mimic or ride on the back of? (4) everything.
