The 3D programmer in me makes me think of how to reproduce this render with signed distance functions. Related to that, Shadertoy is one of my favorite ways to GPU stress test, along with getting some interesting eye candy.
At this point, I just create "renders" by turning Inventors display mode to "Realistic" with shadows and reflections on. Good enough for me. I like seeing good renders but so far trying to make good ones was always too much of a hassle for me. Modelling is just way more fun.
