Coloured paper discs on a flat ground, laid out in a loose grid with a clear margin and a scatter of empty cells — and every one of them built from a single primitive, the half-disc, hinged on its own diameter. A disc is two half-discs sharing one straight edge, and each half is independently absent, laid flat, or bent up out of the sheet through an angle of its own. That one angle does three things at once, all by the same rotation: it foreshortens the half toward its hinge, so the curved edge flattens and the piece reads as card standing proud of the table; it uncovers a crescent of the disc underneath, whose width is a function of the angle rather than a shape anyone cut; and it shears the half’s shadow across the sheet, since the shadow of a rotated plane figure under a single directional light is that same figure under one shear and one scale. So the six things the picture appears to contain — a plain disc, a disc bisected into two colours, a lone half on the ground, a bowl lifted off an underlay, a thin crescent, and an open book with both halves raised around a shared seam — are not six motifs but six values of one triple. Hinge lines are mostly upright or across with a few degrees of wander; the halves of a bisected disc are always different inks, and a raised flap never matches what it uncovers, or the fold would be invisible. One light serves the whole sheet, weak and slightly soft, so every shadow falls the same way and a raised face sits a shade lighter than the same ink lying flat. Flat matte colour throughout: no outline, no gradient, no texture, and no shape anywhere that is not a circle or half of one.
