Once you know how to look at her, you can control which way you want to see her rotate. Stare at her midsection and try and time the way you see her rotating leg. When it comes close to crossing by the pivot leg, you will see how you can start to see her rotating any way you'd like. Once you see it, you cannot NOT see it

Are you guys sure this dancer is legit? I see a "stutter" in the GIF, then she changes direction... time passes, a stutter again with a direction change. Nothing I do in between will changer her direction. When she changes, nothing brings her back... Nothing I do changes her direction, ..she just "changes" :eek:
