That's the Disability Pride Flag I designed (and officially registered as Public Domain) this last Pride Month. The second Sticky!Post on my journal has a plain version for downloading, etc.

Here's what the symbolism means:

The Black Field: Mourning for all those who’ve suffered abuse and violence, because of ableism, also the connection to the pirates’ Jolly Roger flag, and general rebellion.

The five colors (from bottom/left to top/right): the wide variety of types of disability: Mental illness, Intellectual disability, Invisible or Undiagnosed Disability, Physical Disability, and Sensory disability.

The zigzag shape: how disabled people have to always navigate barriers in the normate world & and the creative problem solving we do every day.

The parallel nature of the stripes represent Disability Solidarity, even though our individual needs and experiences are different.
