Electrons in a laser pulse excited semiconductor produce such nice pictures. Isn't that art?
The pictures are the result of the numerical solution of quantum kinetic equations (Kadanoff-Baym equations).

Explanation of the idea of the nonequilibrium Greens functions approach
19 Electrons trapped in a spherical electric field. They form shells like atoms in the Mendeleyev table (notice the symmetry),
and they may "freeze", i.e. crystallize like in this figure.
The pictures are the result of rigorous quantum Monte Carlo calculations.
