By the way, speaking of the possibility to circle through the outer track, I was playing with that idea that you make a few circles around the outer segments reading some features like inner color, then outer color, then length, then blob, AND THEN you move to inner track at the top left corner, and you can make only one circle reading only one feature (either inner color only, or outer color only, or blob only). The longer I think about it the less sense it makes, but it is a possibility, no?  

i think you mean by the left hand that white tile in the upper left corner, if thats the case then i guess that the right hand is the next white tile that appears like rabbit mouth.
