Multi-Reflection test for global and local reflections with fake bounced reflection with multiple reflecting geometry causing lots of different order reflections. Large scale reflecting floor geometry though might be better used with a true mirror texture property since this yields a more accurate reflection under all conditions. For curved surfaces though this achieves reasonable reflections.
