My autistic DGS looked at it and he saw her going clockwise. My DH looked at her and saw her going counter clockwise and after some discussion and him watching for awhile he began to see her going clockwise too and then both directions. But he saw her bottom half moving and not the top half! LOL dont know what that means!!
I noticed if I covered my right eye and watched with my left she turned clockwise. Close my left eye and she turned counter clockwise. I did it several times and it worked every time. Such fun!
