1. A translucent diffuser for an electronic gaming machine for diffusing light from a spot light source, the diffuser comprising an inner portion adapted to be located so as to intercept light emitted along an emission axis by the light source and an outer portion spaced from the emission axis, the inner and outer portions arranged such that, in use, the diffuser prevents transmission of more light in the region of the inner portion than in the region of the outer portion, the transmission of light formed by the diffuser proportionally to an inverse of a brightness pattern emitted by the light source. |
