Moiré patterns

It's lots of fun watching that concentric-circle pattern load; later
data refines coarse jaggies.

Look into the origins of the word "moiré" (é = e-acute in the
Latin-1 charset). Apparently, woven silk is wetted, and laid onto
itself, then the two (?more?) layers are apparently pressed between
two flat surfaces.
The interference pattern between the individual "picks" (?) of the
two layers creates a moiré pattern. (I'm not sure of the details;
might have them wrong, but "watered silk" probably applies.)
