In Spacelength Thought (2012), a typewriter is typing a monologue onto 16mm blank film, projecting one letter at a time against the wall. During the projection, film accumulates progressively on the floor, almost as if—as the artist explains—"in a Turing machine a code were recited mechanically and unveiled through the projection, creating a kind of poetry line—an imagistic form of language: at the same time an enigmatic machine and an openly spread process."

"Barba’s films, installations and publications all raise the question of cinema as a kind of writing" notes the critic Melissa Gronlund, underlining the central role played in her works by the written word and the idea of the physicality of a film projection, usually perceived as something purely immaterial.
