I took some sort of IQ test when I was a kid and there was an entire section that was "if you rotate this object around that axis, it matches which of the followin g options". Try as I might, I can't picture this in my head (picturing anything other than a sphere or a cube is tough) but I found that I could look at the options and logically exclude them in a very tedious way by inspection.
It's one of the reasons I like computer graphics so much: the computer does the rotation for you! Stereo graphics (using the funny LCD glasses) was a true revelation to me, and learning how to rotate things using matrics was another.
You must hate those fancy new style captchas where you rotate the object. I’ve never considered the fairness and discriminatory aspect of captchas until now. I wonder if in the future eternal September will finally end as increasingly complex captchas act as a sort of poll test on posting.
