The prensent invention relates to an ornamental display utilizing particles (40) circulating in the display, in which particles (40) having a small density and having been surface-treated by means of fluorescent material or other reflective material are circulated by the force of air while being lightened, so as to present various ornamental scenes such as a scene of falling snow. In the display, the particles (40) can be circulated even by a smaller quantity of air or a lower electric power, in comparison with the prior art. Moreover, the air is partly introduced through the clearances between the plates of the lower stepped plate assembly (50), so as to easily retrieve and circulate the particles (40), thereby preventing a turbulent flow from being generated, which enables the particles (40) to stably circulate. Further, in the display, partitions (62) having different heights are formed on an upper inclined plate (60), so as to uniformly distribute the particles (40) having been carried to a dropping position located at an upper position in the display. Also, an air emission passage (16) and a plurality of inclined descent-delay plates (18) are disposed under the upper inclined plate (60), so as to reduce the falling speed of the particles (40), thereby presenting a scene of snow falling more vividly and naturally. |
