A wild illusion. The spinning silhouette mostly starts up clockwise for me.
Update (10/14/07): Lots of comments over here at Marginal Revolution. There is a reference to left brain versus right brain dominance, etc., but I’m not too sure … I like the comment about the person that tried filming it backwards … then when played backwards, the person still saw things going in the same direction. 🙂
I could not get her change directions at all …
It started counter-clockwise for me. May be I am too singleminded…
Geez I can’t get it to change directions! Maybe I didn’t try it hard enough.
I can’t get her to spin in the other direction either. Is it supposed to say something about me? Does the right brain – left brain explanation stand or did someone just decide it had to be that because they couldn’t think of anything else?
