How many lines are needed to erase a black rectangle?
How many lines are needed to erase a black rectangle? shows a black rectangle being erased by white lines, drawn by chance. What initially looks like something accidental, without purpose, turns into mutable landscapes and textures. They appear and vanish, until that the figure-ground organization becomes the opposite of the initial configuration. The original black rectangle breaks into many black polygons and, in the other hand, the white progresses, implacably. The works end when the last black pixel is covered by white.
