A mirror with a secret in its reflection

An old bronze mirror holds an image of Buddha that appears on a wall when light shines on its polished face. The picture is concealed within the mirror, not visible as an ordinary design. Tiny distortions in the reflective surface, created during polishing above the hidden design, redirect the light to form the image. A CT scan revealed the concealed metalwork in detail; the picture was built into the object all along.
