We went through different scenes and sure enough, not only did they wobble (when he flew, as if they were made out of dense Jello), but they seemed to switch orientation - the top spike sometimes is off-center to the right, and other times to the left).
I remember this from the original animation, too (I recall sometimes seeing coming out each side of his head). Did Tezuka ever set some kind of "standard" for this -- or IS it a "Mickey Mouse" treatment (you always see his ears at the same right angle -- even though it doesn't make sense from a perspective standpoint)
I've noticed in some "cutaway" art that there are two thingies that look like unfolded paper clips inside each point. Hmmmm....!
