Unprecedented breakthrough in X-ray optics is definitely needed to achieve a picture of an event horizon but...? Such kind of a daydream finally led the development of a Berry-phase crystal waveguide that realizes macro-scopic X-ray translation pallalel to the original beam axis while keeping its angular divergence and wave front. In our SPring-8 demonstration 3.3% of 15 keV X-rays appeared at 0.4 mm away from an incident position on a waveguide, and the propagation was controlled by artificial atomic displacement caused by a piezoelectric actuator. I would review the result and hope to make this seminar our great opportunity to discuss effective future applications of this newcomer in X-ray optics.
