Weird; for me on the first Vid she's persistently clockwise and I can only get it anti-clockwise for short flickers, and on the second one, she's persistently anti-clockwise and only a little bit clockwise.

What does that mean? :/

Maybe it's some sort of strobe effect caused by the frame rate, like in this video: YouTube - Apparent reverse motion in truck wheel lug nuts

That could be it. The second gif does seem to be spinning a little slower than in the video.

HAHA, I got the dancer and the shadow on the ground to go in different directions.

I don't try to do anything that could make my brain spontaniously explode.

I'm able to switch between seeing both on command... I simply look at the reflection of her foot and will myself to believing she's spinning the other way, close my eyes for a second and open, and VOILA! She's spinning the other direction.

All I see is a naked woman spinning towards me. What a tease.. >_>

weird thing is..you like it .___.

Took a couple minutes, but i finally got to see it spin both directions.

That's pretty darn nifty.

i only see it clockwise :/
