I came across the following test.
http://www.news.com.au/couriermail/story/0,023739,22556678-23272,00.html

At first the dancer appeared to rotate in the counter-clockwise direction and after some time
in the clockwise direction.

Is this really the illusion of my brain or some graphics trick/prank?

It is an optical illusion that has nothing to do with left/right brain.

I understand it is an illusion.

But in which direction does the dancer "really" rotate?

Yeah you are right.

But i must say it is a darn good illusion esp. after you see the switch happening.

Hardly, I fail to see the illusion: there was no way in which it appeared to me to rotate in any direction but clockwise. Not after I analyzed the frames, not after I closed one eye, not after I tried envisioning it otherwise. And I'm about as left-brain'd as they come. Although it may have had something to do with my being distracted by the auspiciously erect nipples.

Here's a better illusion: http://www.grand-illusions.com/opticalillusions/dragon_illusion/
This one I've actually constructed in real-life (it sits beside me right now) and works just about 100% of the time.

It's no different than seeing the image in those "magic paintings" from the 90s. You just have to relax your eyes as if you were going to fall asleep and it will appear to change directions. As Thantos said, there is nothing Left/Right brianed about it.

If you see the legs of the dancer or the shadow of the dancer rather than the dancer as a whole you may be able to see it.It worked for me.

Took me a while, but I was eventually able to see it spin counter-clockwise. Not looking directly at the image seemed to be the only way I could see anything moving any way other than clockwise.

EDIT: also weird, if I do manage to see it spin counter-clockwise, I start finding it hard to see it clockwise again. I'd have to look away for a minute or so.
