Each sculpture has three kinds of inter-dimensional space that all occupy the same spatial coordinates: the concrete, volumetric space of the screens; the pictorial/volumetric space of the images produced by the paint on the screens; and the optical interference generated between the screen grids when two or more planes overlap (without coinciding) , an optically real, but tactically non-existent space.
Also very interesting are his works on the streets of Buenos Aires. The photo second from bottom, are two small Animas embedded in a building front, and the bottom photo is from his work 16 Tons, using the prison window grids of a Buenos Aires prison as a pixelated screen. By breaking out certain windows, images of faces appeared reflected in the remaining panes. Very cool and creepy.
