No. Wiggles didn't shrink. I screwed up taking the picture. In the picture above, the ruler is closer to the camera than the snake is. That makes it look relatively larger. Our brains understand this. The computer's brain doesn't. So, if you use Serpwidget to get a length on your snake, you need to make sure that the snake and the ruler are the same distance from the camera, as I did when I first tried Serpwidget (pic below).
