Mississippi State's T.K. Martin Center for Technology and Disability hosts project EXPRESS Yourself, an art project that helps provide a means of self-expression to people with significant physical disabilities. Using techniques developed by Tim Lefens of Artistic Realizations Technologies in Princeton, N.J., "trackers" function as the arms as the "hands" of the person creating the art. Judy Duncan, in the foreground, serves as a tracker. Artwork can be purchased at the center's gallery.
