Im the realist and see booth movements (clockwise and counter-clockwise). It depends on your own recognition of the THINGS. This is impressiv because it shows us the dualism system. If we would teach our brain in creativity and logic in the same amount then everybody would see the both spinning situations.
I believe in left/right brain dependencies because this ist also teached from old traditions.
Unfortunately most of us lost all those old traditions in mind and lots of people give a sh*t on this....
