It's a light which you can change the color and the shape of.
The state of the light is synchronized between users by sharing the state of the color and the shape using sync variables.
It plays scaling animation of the light when the black lamp shade is being onUsed.
When the white part at the back of the light is onUsed, the color of the light will change.

local color_state=0 --0　White　　　Others: the state of color.
