This is what the dodecahedron would look like viewed from the inside with spherical mirrored walls. At certain dihedral angles, this resembles a Poincaré projection of 3D hyperbolic space tiled with ideal dodecahedrons. Notice that when the space becomes elliptic, a “hole” opens up in the center. This is because the space loops around on itself causing objects beyond the “maximum distance” to appear larger because they are actually closer. Weird huh?
