The OSP Spins program can be configured to show user-created quantum-mechanical spin experiments. These configurations can be saved in xml files and then loaded as shown in this example.
Double-click the green arrow in the navigation page. The Spins Custom Configuration node shows an experiment where the oven produces a particular, pre-programmed, superposition of spin-1 eigenstates. This can be done in either the x, y, or z basis. Here we have chosen the z basis and the state made up of 25% up, 50% up zero, and 25% down (= (1/2)[z+> + √2|z0> + |z−>]). In general, ANY configuration can be saved: spin-1/2, spin-1 or SU(3), multiple ideal analyzers, initial superpositions, interferometers, etc. The blue analyzer's orientation can be changed by clicking it.
