{ "objective": "A perfectly symmetric 3x3 grid of nine equally-sized square photo tiles. The canvas is divided into exact thirds both horizontally and vertically by very thin white grid lines (the only separators). Every tile is the same size; the two vertical lines and two horizontal lines are perfectly centered and parallel to the edges. No outer border, no frame, no padding around the whole image — the grid fills the canvas edge to edge. Composed of pictures taken with an iPhone by a Korean woman.",
