Despite the title, this is not a post about New Labour, but about this lady…
No, I’m not just a perv posting silhouetted computer generated naked woman spinning for kicks. The strange thing about this is that you can see the woman spinning either clockwise or anti-clockwise. The article I got this from claims this has something to do with whether you are left-brained or right-brained, but that’s probably nonsense. You can also flip from seeing it one way to seeing it the other way. The way I got it to work was to look at the ‘reflection’ at the bottom, and try to convince myself that when I thought the upper foot was at the back, it was actually at the front. After a few spins, the woman at the top starting spinning the other way. From then on, she stayed spinning that way quite stably until I focused on something else and then looked back.
FWIW, I naturally see her spinning clockwise, which apparently means I use the right hand side of my brain more than the left (contrary to most people, according to the article). A quick search on the internet suggests this means I am visual, intuitive, etc.
Update: Just scoured the internet to see if anyone had written anything interesting about this, and the answer is: not really. Two pages did stand out though:
- This one from NeuroLogica blog, which like me takes a pretty dim view of the whole left/right-brained thing
- This one which shows two slightly modified versions of the animation side by side. Minor cues have been added to bias your interpretation of the image one way or the other, and they’re completely effective.
