Raymarching inside the Seifert-Weber dodecahedral space, a closed hyperbolic 3-manifold formed by identifying opposite faces of a regular dodecahedron with 3/10 turns. This is one of the first known examples of a closed hyperbolic 3-manifold. The scene shows the interior with copies of objects visible through the face identifications.
