take a look at this spinning silouhette. Which direction is she spinning? clockwise or anticlockwise?
The truth is, she can be seen as spinning both ways.
If you see her spinning clockwise, that means you're using the right side, or more creative side of your brain. If she appears to be moving counter-clockwise, then that means the left side, or more logical side of your think muscle is superior.
It is possible to force yourself to look at her spin clockwise/anticlockwise though. Took me awhile but i managed to do it.
The trick is to stare at the shadow she makes on the floor.. you can either picture the outside foot shadow going further away (clockwise) or picture it coming towards you (anticlockwise). Once you have that pictured then slowly look up at the spinning silhoutte and it'll be spinning in that direction you tried to picture it as.
See if you can do both anti/clock wise! :)
I dont quite know what the explanation is for this, perhaps it's because she's all black, and our depth/perception is impaired. Pretty darn cool . :)
basically look at the spinning wheel first. note the direction which it spins. then stare at the centre black dot for a while.. the spinning wheel will change direction. :)
rinse and repeat
wahhaaha
