How do you explain the periodical reversing of all these 'illusions'? Check out the rotating spheres where there is no illumination or depth cue. Jack is a member of the Royal Society or FRS so he is no lightweight.
By the way the period between reversals is observer dependant. It is not about left/right hemisphere dominace but an oscillation where each is dominant in turn. This can be modulated by external magnetic fields!
