What's this!? A cycles render!? Could it be!? Yes it is true. I used cycles for this render, but merely to just capture this effect of gravitational lensing. I had to do quite a bit of node work feeding into a refraction shader. But in the end, it turned out well. Even better, no noise! YAY! Tell me what you guys think. (Just a little fun thing, press space to reverse the path of the black hole)
