Note: In W. Mark Sutherland’s Code X (2002), a born-digital sound poetry machine that allows users to create their own sound poetry performances, a line is drawn between the work and a history of sound poetry, performance art, and concrete poetics. Code X is a digital game that marks a point of convergence between many art forms. As Paul Dutton writes of Code X in a brochure for Sutherland’s Scratch exhibit at the Koffler Gallery in 2002 (archived on Sutherland’s webpage), the work “fuses poetry, music, and visual art” to reveal the tenuous boundaries between art forms.
