de-finition/method: this takes place in the room with the largest wall in a site with many rooms. this largest wall will present the matrix of the work. the wall is covered with as many canvases as possible painted the same color as it is. these canvases constitute a stock, a sort of distributed stack, from which canvases are taken and hung in the other rooms of the site or at other sites, near or far. the matrix must be hung for an extended period at a fixed address. the canvases taken from the stock will, ideally, be hung in a single room or even on a single wall. and no matter where they end up, the wall or walls on which they’re hung will be painted a color other than white, and the rehung canvases will be painted the same color. when a canvas is removed from the matrix wall, a small canvas, like the replacement notice in a museum, will be hung in the empty space it leaves behind, and will be painted the same color as the exiled canvas. no canvas can be permanently removed from the matrix wall. actualization(s): 1992 : le consortium, dijon, france 1998 : centre pompidou, paris 1999 : centro andaluz de arte contemporaneo, séville, espagne, 2012 : le consortium, dijon, france (permanent), 2020 : le consortium, dijon, france (permanent)
