Which surfaces can be realized with two-dimensional faces of the five-dimensional cube (the penteract)? How can we visualize them? In recent work, Aveni, Govc, and Rolda ́n show that there exist 2690 connected closed cubical surfaces up to isomorphism in the 5-cube. They give a classification in terms of their genus g for closed orientable cubical surfaces, and their demigenus k for a closed non-orientable cubical surface. In this paper we present the definition of a cubical surface and we visualize the projection to ℝ³ of a torus, a genus two torus, the projective plane, and the Klein bottle. We use reinforcement learning techniques to obtain configurations optimized for 3D-printing.
