Today, I see the ballerina going clockwise, and I saw the second and third scenes much as you intended. Not the first though.

About a third of the time, I see the ballerina go the other way. It depends on what I've been doing right before I look at it. I've had the mind-breaking experience of seeing it go anti-clockwise, looking away for a moment, and when I looked back it was clockwise. O_o

So, in conclusion: I am weird. But also: you seem to be onto something.
