CUAG has developed an audio description tour for "Drift: Art and Dark Matter," designed for gallery visitors who are blind or who have low vision. It is intended for in-gallery use, but can also be used remotely. "Drift: Art and Dark Matter" is a residency and exhibition project generated by Agnes Etherington Art Centre, the Arthur B. McDonald Canadian Astroparticle Physics Research Institute and SNOLAB. For more information on the exhibition: cuag.ca/exhibition/drift-art-and-dark-matter/ The tour provides an overall description of the exhibition, and a description of the installation "n-land: the holographic (principle)" by Jol Thoms. The descriptions are accompanied by interpretations and further prompts for connecting with the themes of the exhibition. This tour was produced by CUAG, in collaboration with Carla Ayukawa and eight members of the Ottawa blind and low vision community. It was developed as a Creative Access Working Groups project, funded by a Canada Council for the Arts Sector Innovation grant, in partnership with Critical Distance Centre for Curators and Tangled Art + Disability. It was also supported by the Mame Jackson Experiential Learning Fund.
