An example gravity well showing how our Sun warps spacetime to bend light from a distant star, shifting its apparent location when observed (at a great distance) through a spacefaring telescope.
Thoughts?
Using Blender 2.7, the Compositor, and Cycles. The materials are public domain metals found on BlendSwap.
Looks nice! Might be cool if you show the light beam on the surface of the warped spacetime to display the correlation between the well and the bending light
