| Title: |
Display System Using Projection Screens Formed of Flowing Snow |
| Abstract: |
A display system for use in winter and other low temperature venues. The
system includes a projection screen generation assembly that includes a
snow making machine. The snow making machine receives an input flow of a
liquid, such as water plus one or more additives to increase opacity
and/or reflectivity of the snowflakes. The machine forms snow from the
input flow and discharges a volume of flowing snow as a sheet or curtain
providing a projection screen. The system includes a high-brightness
projector directing light onto the projection screen to provide an image
on surfaces of the flowing snow. In some embodiments, the snow making
machine includes a nozzle configured such that the flowing snow is output
in a substantially planar sheet, e.g., with the use of a diffuser or the
like for increasing the laminar nature of the flow and the sheet may be
relatively thin.
