This animation shows the probability density of a Gaussian-shaped wave packet excited with high momentum in the infinite square well potential.

The wave packet shape slowly decays curing the first five periods of classical periodic motion inside the potential well.

More information on wave packets in the infinite square well can be found in the paper:
