Well, square waves give rise to lots of harmonics which can be useful.
But what about triangles and sawtooths. Any interesting properies

Periodic waveforms are all boring. They just do the same thing, over
and over.
A complex pulse can do interesting things. Spin an airplane. Fuse
deuterium-tritium. Trigger a megaton boom.
With the right effectors to translate the electrical waveform into the
physical displacement of moving mass.

computers now.
But if you don't know enough to understand what the computer could be
telling you, the computer is less helpful than it might be.

There may be an easier route through more easily comprehended computer
graphics but I've not seen any evidence to suggest that it has yet been
found.
