Versenyfutás (Lábas Zoltánnal); Interakció 2 kamerára, magyarázattal) & Parallel Lines; Interaction for Four Cameras (with Erdély, Berényi, Lábas) (Párhuzamos vonalak; Interakció 4 kamerára, közrm?köd?k: Erdély, Berényi, Lábas)

Dóra Maurer—painter, filmmaker, photographer, and longstanding professor of art in Budapest—works within a framework of geometric abstraction grounded in 1920s Constructivism and its postwar revival as a form of performance art in Latin America and Eastern Europe. Parallel Lines is one of many investigations in “living geometry” that Maurer undertook beginning in 1972: here she asked a student to run against her on the opposite side of an apartment block balcony, each snapping pictures of the other side at predetermined points in the race. The top and bottom positions are switched in the final mounted version, which also includes a second camera “interaction,” in which the two protagonists alternately face and run past each other in a park.
