We have created a suite of open source programs that numerically calculate and visualize the
evolution of arbitrary initial quantum-mechanical bound states. The calculations are based on the
expansion of an arbitrary wave function in terms of basis vectors in a reduced Hilbert space. The
approach is stable, fast, and accurate at depicting the long-time dependence of complicated bound
states. Several real-time visualizations, such as the position and momentum expectation values and
the Wigner quasiprobability distribution for the position and momentum, can be shown. We use
these computational tools to study the time-dependent properties of quantum-mechanical systems
and discuss the effectiveness of the algorithm.
