The Gadsden Flag has been endlessly reinterpreted, modified, parodied, and generally played with, as the following examples show. The design violates a number of basic principles of good flag design, but its ability to capture the imagination and spur creativity shows it to have become a very effective flag nevertheless.

Specific “rights”:
Porcupines:
Simplifications:
Parodies:

Strangeness:
René Magritte knows a thing or two about the Treachery of Images.

This psychedelic DTOM flag by Stephen Richard Barlow (on Deviant Art) owes more to the so-called First Navy Jack than the Gadsden flag, but is too strange not to exclude.
That might be the most entertaining flag meme extant.
