Abstract: What is particularly worthy of illustration is that, the interlacing meshes of the upper circle and the lower circle are arranged in S-shaped curves, in both inner positions and outer positions. The purpose of the arrangement is that, the glass rods are inserted into the meshes, and slots are formed between the glass rods; and pass through the slots is the light, which is partly hidden and partly visible. Therefore, it creates a polychrome, phantom, project light source.
