Friends,
One of my colleagues here forwarded the attached image file to me
and asked if I could explain why the dancer is sometimes seen as
spinning to the left and sometimes to the right. I don't buy the
left brain/right explanation that came with it, but I have no real
idea why it works. Can anyone help me out?
Thanks,
Larry
Cool demo....
I can actually make her pan right to left, left to right - just going
back and forth and never doing a complete circle...
I think it is a classic figure/ground kinda thing. The key to
getting her to reverse directions is seeing that the leg is in the
foreground (in front of her body) or the leg is in the background
(behind her body). With a bit of practice I can do it at will...
No left/right brain thing here at all
