It means you are completely logically-minded and aren't really creative....just kidding!
I would try again later. Perhaps you would be able to see it the other way. I do think it's interesting how "monkeygirl" (sorry forgot name) and I both saw it clockwise until we started reading it.
From a psych perspective, it would make a very interesting study to compare some of these illusions with various type of standardized cognitive tests. Does it measure cognitive flexibility, is there truly a component of "left vs right brain," does it have something to do with eye tracking, does it vary depending on what we looked at first (i.e., the top of the picture, the bottom, the middle or read the print first)...? Just quickly pulling ideas from my very tired brain.
