On a stage (28) floor (30) in the middle section thereof there is arranged a reflecting surface (18). Between the stage (28) floor (30) and ceiling (32) all over the width thereof extends a transparent smooth foil (20) the bottom end of which is fastened at the spot between the reflecting surface (18) and background. Said foil (20) upper end is fastened on the ceiling (32) at the spot lying further forward. On the ceiling (32) in front of the foil (20) upper end there is situated a projector, which is fastened there and which is directed toward the reflecting surface (18). The foil (20) forms with the stage (28) floor (30) an angle of 45 degrees. In front of a computer being controlled by a light intensifier (12) there is arranged a mirror (14), toward which the light intensifier (12) is directed, whereby the mirror capturing light emitted by the light intensifier (12) is directed toward the reflecting surface (18) and projects light thereon.
