Imagine living on a cat photo (like jasondavies.com/catmap ), you can move on the photo or also in the third dimension, warping the distances according to Arnold's Cat Map... Well, this is how this 3D space looks from the inside.

$Changing Curvature More experiments with curvature changing. The first scene is a ring of {3,5,3} dodecahedra in spherical geometry (10 out of 120). Then we glue {3,5,4}, {3,5,5}, ..., {3,5,∞} dodecahedra in the same way (we also do fractional rs, and we end at {3,5,196608} but there is no visible difference). We deal with the ultra-ideal vertices like in https://youtu.be/oKopsPT-NXA$
