Hopefully your new year’s hangovers have now passed because following hot on the heels of the freaky reversing ballerina..
comes another ambiguous spinner.. click on the image to see the movie of a point light figure walking in a circle..
as before, you ought to see the figure reversing the direction from clockwise to anticlockwise and back again. Chances are the reversal happens faster than with the ballerina. While your head is still spinning remember that nothing changes in the movies themselves, it’s all trickery in your head.
