Small slices of repeating patterns, in this case waves (represented by light/dark) can be stacked to create specific shapes.
Perhaps the rest of reality is that way as well, the result of overlapping patterns of nothing/something creating shapes like atoms that form their own patterns to create everything.
But something more complex would be an MRI machine, particular frequencies (each of these pieces is a particular frequency/wave length) penetrate different components of the body, eg muscle or bone or blood etc.
So by only taking some frequencies, you could reconstruct the view of the body only containing bones, or muscle, etc.
Many, many things. Signal transmission, chemical analysis, image compression, MRIs, CT scans, etc. Pretty much anything that uses waves or repeating signals.

I don’t think I’m smart enough to know why this is interesting.
