When I worked on this project at the Wolfram High School Summer Camp, all of the 3D shapes created by Cellular Automata rules had only one cell "alive" in its starting iteration, so the possible classifications for the shapes were Sphere, Cube, Less Interesting Irregular, and Interesting Irregular. Since then, I have generated shapes with multiple cells "alive" in the beginning, which creates rectangular prisms, but the Classifier function including these shapes is not as accurate as I would like it to be which is why I have not added these results to the community post yet. My project mainly uses the Wolfram CellularAutomaton function, which uses only cube cells, so I have not used hexagonal prisms.
