Where do people get this "no depth cues" claim? The way her lifted leg moves suggests so obviously a clockwise motion that even Alicorn's link can't make my brain see the counterclockwise motion for longer than a round or two at most.

I mean, the only way the perspective makes any sense is if the lifted leg is furthest away when it's the highest up in the 2d image. Yes, the shadow/reflection is all wrong but for some reason my brain just refuses to give that priority.

What cues do others use? I'd love to see variations of this image with different cues present/absent/reversed.

ETA: I'm no longer sure that the reflection is wrong. But something about the image is off.

Edit: typos
