@maxpoolma𝕏pool - cool painting. Not enough four-dimensional art out there.

There could be more 4d art... the structures are there, waiting for artists to explore them.

The 120-cell has 120 regular dodecahedra as 3d faces. Then cut across the vertices, edges, and 2d faces and you get the "runcinated" 120-cell shown below.
