Edge of Vision

Many of you have probably seen this animation of a spinning dancer silhouette from the Daily Telegraph, as it’s been making the rounds on various blogs and social networking sites. It’s a neat animation, but the blurb also states the following:

The Right Brain vs Left Brain test … do you see the dancer turning clockwise or anti-clockwise? If clockwise, then you use more of the right side of the brain and vice versa.

Personally, I can’t think of anything that would back up their source-less assertion, and a quick literature search doesn’t turn up anything either. I’ve chalked it up as a yet another misinformative popular-press write-up, but was wondering if any readers had further insight.
