The Intersex Flag?
The flag was created in 2013 by Morgan Carpenter of Intersex Human Rights Australia (then known as Organisation Intersex International Australia) to create a flag "that is not derivative, but is yet firmly grounded in meaning". The circle is described as "unbroken and unornamented, symbolizing wholeness and completeness, and our potentialities. We are still fighting for bodily autonomy and genital integrity, and this symbolizes the right to be who and how we want to be."
The organization describes it as freely available "for use by any intersex person or organization who wishes to use it, in a human rights affirming community context."
