Steganopgrahy isn't _only_ the practice of altering the encoding of a digital
image in order to embed non-visual data within it; it can also be the act of
arranging the subject of the image to encode information for the viewer. It
needn't even be an image.

When Jeremiah Denton blinked TORTURE in morse code he was engaging in
steganography; one could discuss the particular details of a purchase order,
and those details could double as revealing information for something else
altogether; or one could print a comic where the stippled colours also encode
binary information in their dots. And so on.
