Spinning girl optical illusion

June 30th, 2007 - 16:35 | 4 comments

One of the most impressive optical illusions I’ve seen in a while. Which way is she rotating? She started off clockwise for me, but is now firmly anti-clockwise and won’t change back for more than a second or two. I managed it by looking at the edge of the screen, rather than concentrating on her shadow, but ymmv…

Update: Re-reading the above, I see I didn’t really express how amazing this illusion is. Usually with ’switching’ illusions I can see how it works - that is, which part of my visual system is getting confused, and how the image is constructed so as to create the effect - but this one’s a mystery to me. It’s completely unintuitive. I haven’t had a good dig around the site yet; I got stuck on this one and haven’t progressed further. Anybody?

I got the hidden tiger immediately but the spinning girl just spins anti-clockwise for me.

I found blinking twice quickly could swap the direction for me Focus on thinking about the legs and which one would go in front of the other if going in the other direction and blink

We found the tiger! The spinning girl was all over the place at first, but now refuses to deviate from anti-clockwise =P
