Ah, got it. Well according to SR all motion or stillness is an illusion. But I think a better analogy would be calling someone by a different name because when they are moving their face looks motion blurred.
One important point is that if a magnetic field is created by a net charged object in motion, if SR is correct then a magnetic field that occurs in one reference frame does not occur in a co-moving frame. Magnetic fields are a useful fiction, but hardly real.
