If you haven't seen PoC||GTFO 0x14, run over to
https://www.alchemistowl.org/pocorgtfo/ and have a read.

It features Postscript, PDF/JPEG, and GIF MD5 quines (where the MD5 hash
of the document appears in the text of the document itself) and is itself
an MD5 quine in two different ways (PDF and NES ROM polyglot).
