左脑、右脑

最近在电视广告上看见了一则有趣的旋转舞者，spinning dancer的广告。

早在1年前我就在网络上看见这有趣的短片了。这个动画的设计者是Nobuyuki Kayahara。

广告如网络流传的一样，说明这是一个左右脑的测试。其实这个说法还有很大的争议性，准确度也被怀疑，所以大家别被误导了！

The illusion has been incorrectly^[3] identified as a scientific personality test that supposedly reveals which hemisphere of the brain is dominant in the observer. Under this unproven interpretation, it has been popularly called the Right Brain–Left Brain test,^[4] and was widely circulated on the Internet during late 2007 to early 2008.

但是，不同人的确会看到不同的旋转方向。我是一直看见女生在转换方向呢！
你呢？又看见了什么？
