The Improbable Research blog tipped me off to this important study:

Excess of counterclockwise scalp hair-whorl
rotation in homosexual men

It was recently discovered that the human right-versus-left-hand use preference and the direction of scalp hair-whorl rotation develop from a common genetic mechanism. Such a mechanism controls functional specialization of brain hemispheres. Whether the same mechanism specifying mental makeup influences sexual preference was determined here by comparing hair-whorl rotation in groups enriched with homosexual men with that in males at large. Only a minority of 8.2% (n = 207) unselected ‘control’ group of males had counterclockwise rotation. In contrast, all three samples enriched with homosexual men exhibited highly significant (P < 0.0001), 3.6-fold excess (29.8%, n = 272) counterclockwise rotation. These results suggest that sexual preference may be influenced in a significant proportion of homosexual men by a biological/genetic factor that also controls direction of hair-whorl rotation.

Took me a minute before I saw any circles and they tend to disappear if I actually look at them.

As for the other matter, that sounds like an odd marker to look at but certainly not a meaningless study.

16 or 25 if you count the ones going horizontal from the squares, I don't think they're complete so I'm going to say 16.
