Obstacle consists of two video materials projected in a continuous loop. A tracking shot along some high garden walls, accompanies the image of a boy pulling a carriage behind him. The boy’s movements are synchronized with the changing rhythm of the passing walls. The ride continues through the outskirts of the city, where common property walls become an exclusionary system, obstructing us from communicating within. The technological connection between the two projections does not allow the situation to be resolved.
