The Spectroscopy Lab Suite has a number of similar activities

Visual Quantum Mechanics contains a series of simulations, tutorials, and pedagogy to help in the learning of concepts in quantum physics.  This material is suitable for a wide range of students.

This conference proceeding contains a paper which reports the effectiveness of implementing elements of the Visual Quantum Mechanics in the high school and introductory college physics class setting.

The Hydrogen Spectrum tutorial uses this tool to relate observed emmision spectra to transitions between atomic energy levels.

Gas Lamp Absorption complements Gas Lamp Emission by allowing the learner to perform the same electronic transition activities while observing the absorption spectrum.

The Gas Lamp Emission activity involves one less energy level and allows the learner to select atomic gas sources other than Hydrogen.
