One "modern" solution to making snow on stage, or in a display or retail environment, is the fluid-based snow machine such as the Little Blizzard from CITC.
When paired up with the Hurricane fan, the Little Blizzard creates the perfect storm (shown at right) - a continuous floating snow effect that evaporates on contact.
The Little Blizzard can be run for extended periods of time without overheating. It is insulated for noise control and has a flake size adjustment paddle, two-speed motor, remote control and DMX on-board.
The Little Blizzard line of fluids creates an extremely dry flake that floats over long distances. The water content evaporates quickly leaving a beautiful falling flake that is dry to the touch and disappears after contact leaving no residue or mess. 
The Little Blizzard is available for rental ($115/week) or purchase. The Hurricane is also available from Limelight.
