Abstract
Ornamental display device for simulating snowfall over a display object or scene positioned within a housing comprises a liquid filled compartment rotatably arranged within the housing. The compartment includes first and second opposed sidewalls having aligned transparent portions defining a sealed interior cavity for receiving the liquid. The liquid within the cavity is substantially transparent and a plurality of snow-simulating flake particles are dispersed within the liquid. Blade members radially arranged within the compartment are oriented at a predetermined angle so as to transport flake particles from the lower zone of the cavity to the upper zone as the compartment is rotated. The transparent sidewall portions are aligned with the display object or scene so that the object or scene can be viewed during continuous recirculation of the flake particles.
