The work of Francis Alÿs finds place in the interdisciplinary space of art, architecture, and social practice. In Pacing, the Belgian artist drew invisible figures through the public space of post-9/11 Manhattan as a form of imaginary architecture. Although the act itself has no goal, this mode of movement becomes a way in which Alÿs conveys the acts physicality by defining specific tasks that also have certain historical resonances and cultural implications. To use ones steps as a measurement to establish a route between two points is a sentimental mapping of sorts, an intuitive act embodying our representation of the world in relation to sensorial experience.
