Well, the image moves when you try to trace it, because your eyes are jumping around. Then, when you've got a wrong line, your brain tries to fit the imagined image to the wrong line by skewing it, which it does in several different ways once you've got enough wrong lines, so the wrong lines multiply. A skilled artist can work around this, by drawing the right lines (and erasing / ignoring the wrong lines). |
