摘要
Audio-vision ball consists of two joined half balls of "Plexiglass brown 400" (RTM) (I), and a matt disc that is placed between the half balls, consists of "Plexiglass white 017", and acts as projection face for film and transparency projections. The picture is freely visible in space. The sepn. between the ball, and the space in which it is suspended, is increased as a result of the use of (I). There is low dependency on the light in the space.
