Three


A black square. In the central ninth there's a sticky note, square with slightly irregular edges, and a small notch near the right end of the bottom edge. It bears text written roughly in thick black marker pen, not clearly distinguishable, centred over 4 lines: “29 × 55 × 93” / “148.335” / “112 × 44 × 20” / “98.560”. The note appears white, grainy, dithered from almost-all bright white at the right, to almost black at the left.
