Video of single electron buildup of a two-slit interference pattern, by Akira Tonomura, Junji Endo, Tsuyoshi Matsuda, Takeshi Kawasaki, and Hiroshi Ezawa.

Recommended software:

InterferenceSimulator, a program demonstrating quantal two-slit Fresnel interference patterns with one, the other, or both slits open. A magnetic flux situated between the two slits allows demonstration of the Aharonov-Bohm effect. Simulations with short de Broglie wavelengths illustrate the classical limit of quantum mechanics. Documentation for InterferenceSimulator (PDF).

Quantum mechanics simulations from PhET, particularly Quantum Tunneling and Wave Packets.

Physlet quantum mechanics. (In particular, the simulation of revivals. Particularly interesting if you click on "Start p0 = 40pi".)

Numerical solutions to the quantal energy eigenproblem for a finite symmetric square well. The Excel spreadsheet used to produce figures in section 5.1 of Invitation to Quantum Mechanics. Play around with this spreadsheet to get a better feel for the significance of energy eigenfunctions.
