SCP-104 is a sphere, 35.5 cm (14 in) around and weighing 2.3 kg (5 lbs). The outside is glass and very smooth, coating the sphere in a layer 6 mm (0.2 in) thick. Under this layer is an extremely intricate design of very thin black and white lines. This inner “core” is a delicately carved ball of wood, giving slight texture to the line design. The design itself is unimaginably complex and seems to form something of a Rorschach test, as all viewers seem to have a different interpretation.
