A story of inclusiveness and collaboration through mathematics and art. A inmate of a North American prison taught himself mathematics, then went on to study more and more and contacted the author. He then planned and realized together with other inmates, a piece of art reproducing a medieval pattern as studied mathematically. As the art is modular, several other inmates could collaborate. The math was necessary as a nontrivial stimulus, and so was the piece of art.
