MacMolPlt can display many types of orbitals, on this page are several examples of orbital display for localized moelcular orbitals for the water molecule. The first is a O-H bond illustrated with both a 2D contour map and a 3D wire mesh surface.
The illustrates all of the valance orbitals including both O-H bonds and two lone pairs on the oxygen. Note that each orbital is assigned colors independantly thus all four orbitals are easily distinguishable based on color.
Finally click here if you have a 3DMF browser plugin to download a model of the system illustrated above which you can rotate and scale on your local machine.
