#### Looks_like

Normally the light source itself has no visible shape. The light simply radiates from an invisible point or area. You may give a light source any shape by adding a `looks_like {` OBJECT `}` statement.

There is an implied `no_shadow` attached to the `looks_like` object so that light is not blocked by the object. Without the automatic `no_shadow` the light inside the object would not escape. The object would, in effect, cast a shadow over everything.

If you want the attached object to block light then you should attach it with a `union` and not a `looks_like` as follows:

      union {

        light_source { <100, 200, -300> color White }

        object { My_Lamp_Shape }

      }

Presumably parts of the lamp shade are transparent to let some light out.
