"A man paints with his brains and not with his hands."
Friends in Art (FIA)
Affiliated with the American Council for the Blind, this organization promotes accessibility to the arts for people who are blind and visually impaired. Among many other things, Friends In Art offers an annual scholarship to burgeoning artists in college or art/design schools. During the ACB annual convention, FIA offers an "art parlor" in which artists can exhibit their works. They also offer workshops to hone artistic skills.
Several other organizations focus on access to the arts for people with disabilities in a broader sense, but that is a topic for another day.
