All I see is the default girl from Poser 4... *giggles madly* I am such a dork that instead of checking what the poll was about, I marveled at the fact that I could ID which 3D model they had used to make the animation with.
...for the record, though. I can make her switch at will. I close my eyes a sec, she's going one way. Do it again and will her to go the other way and she does.
