Created in Bryce 7 Pro from a boolean made of a sphere intersected with 6 negative spheres. The resulting object was then lowered into the mirror rendered ground plane so that only 50% was visible. A squashed half sphere mirror shell was placed behind the object and angled at 22.5 degrees above the horizontal. A pre-set Mordor sky was selected and modified slightly by changing the sun position . . .
Created and rendered on my trusty MacMini . . .
No post-work . . .
