"Truly" may be too strong an adverb, but I meant something not obtained
with the aid of a computing device.

I do like Ron Garret's suggestion.  I take a photo of some scattered
leaves in the woods behind my house, and then:

patrick at laptop:~$ gpg --print-md sha256 scattered_leaves.jpg

# Then FWIW:
patrick at laptop:~$ shred -u scattered_leaves.jpg

It does involve a computing device, but with an excellent seed.
