Experts may want to cast an eye over the open-access paper Buser, Kajari & Schleich, "Visualization of the Gödel universe", 2013 New J. Phys. 15 013063 <https://iopscience.iop.org/article/10.1088/1367-2630/15/1/013063 https://iopscience.iop.org/article/10.1088/1367-2630/15/1/01...>. Be sure to also see the supplementary data, which contains several videos of their ray-tracing and schematic animations <https://iopscience.iop.org/article/10.1088/1367-2630/15/1/013063/data https://iopscience.iop.org/article/10.1088/1367-2630/15/1/01...>. (I think movie 11 is the most interesting, and props to anyone who (with the computational resources available a decade after this visualization) substitutes in a ball of a gamma-decaying substance, tracing out the evolution of its emissions.)
