...this facilitates more accurate alignment with the layer below as the upper layer is being rotated and aligned with the layer below.
the see-saw effect is just a matter of making the sure that the subject is aligned in the middle and copying the sequence of layers (mirrored and reversed for the 2nd half of the animation)
EDIT: depending on the size of the original GIF I will sometimes increase the dimensions of the entire set of images by 400% to make for even more accurate alignment of frames. When it is all done, I will then reduce it back to the original dimensions
