You can see hundreds of little images of yourself in the Orbs. Oh yeah, the light. The light activates the Orbs. With the light on, they sing. A pleasing, soothing harmonic drone builds and carries through a crowded room.
People wonder what that sound is.
The Orbs are hard to miss. Hard not to approach. Even without the drone. When you stand at the Orbs you notice that when you bend to look inside, you hear a stereophonic rustling of chimes. You pull back.
