I did a blender art! It's embedded just below, as you can probably see :p

It took waaaaaaayyyy toooooo long to render smthn like 10 hours. I should have rendered while I was sleeping tbh, would have been less painful. Ah well. I'm super happy with the output nonetheless. A bit of a note on how the effect was pulled off with the outer "cube", I used a boolean modifier with a sphere in the middle to get the shape, and the material is a simple glass shader with the ior set to that of cubic zerconia. The lighting comes from simple colored spotlights distributed throughout the scene pointed at the outer cube.
