Anecdotally it seems like it can be pretty easily trained. It took me a few minutes to get it to switch at all but from there it was pretty easy to go from having to stare at the foot to having to look away to having a specific time in the rotation to be able to alternate (almost) at will. Of course if it was an animation of the shadow of a turning teapot I probably wouldn't have bothered so there's that.
