excellent purple dot illusion

If you stare at the little black cross in the center of this ring of blinking
purple dots, the dots will turn green and eventually disappear. But if you stare
at the purple dots themselves, you'll see that they only blink off momentarily
and are never green. Link (via Random Good Stuff via BoingBoing).

But is this interactive?

I believe it is. The fact for cinema for example is that little new expressions had been added since late '80 last century until great psychological discoveries were understood by the small group of promising ones of cinema. Embarrassed as it has been, however, is Psychology itself too is young and so many temporal hypothesis are yet under questioning. All I want to say is people are at the gate of the treasures of vision as well as releasing the power of them.
