This has color coded 3D cut-away views of the spherical Schroedinger electron probability densities (making it 4D with 3D objects). The color is based on the l (angular momentum) quantum number. The X-Y-Z position is based n,m,s(pin) quantum numbers. A fully interactive version of this is available at theoryofeverything.org on pane #8 of this Mathematica CDF demonstration.
