At least one target (10, 11) is caused to move with complex motion combining rotation about an axis (5) which is approximately horizontal and translation along a direction which is approximately perpendicular to said axis (5) behind an opaque panel (3) delimiting a window (4). By giving suitable directions, amplitudes and speeds to these respective motions, the apparent motion of the target as seen through the window (4) is pseudo-random in time and concerning its trajectory between two passes behind the panel. This increases the difficulty, and hence the attraction of target shooting.
