The Supplemental Material consists of:

1. Three movies displaying the space-time evolutions of the rectangular
wavetrains observed in experiments and of the box considered in the numerical
simulation.

2. A pdf document providing additional information about Fourier analysis of
the experimental data for the interested reader.
