The projected light patterns are formed by providing a lamp within a base and rotatably mounting a dome over the lamp and substantially on top of the base. The dome is made out of translucent material which is patterned with a semi-opaque coatings so as to form light patterns on the dome itself and project the light patterns on adjacent ceilings and/or walls of a room.
