Generation of hybridised orbitals from s- and p-atomic orbitals 

Program to plot different hybridised orbitals sp, sp2, sp3, sp + 2 p-orbitals (as in ethyne), and sp2 + 1 p-orbital (as in ethene). The lobes are purely schematic and do not follow true quantum-mechanical wave functions, as these are anyway approximate for multi-electron atoms.
