Concept: "Snowstorm in China" + Ellusionist's "Pyro".

Movie scene (requires CGI):
All of the confetti burn into the image of the spectator's thought of card/person/number.
Confetti flying in the air. The lights go out. Confetti is actually glowing in the dark. As it forms an image of a kind looking girl, the "Pyro" ball is shot in the air and this is seen transforming into a powerful woman. Scene would be probably part of a sequence where a magician/shaman is narrating a story to the protagonist (something definitely philosophical).
Air conditioner in the middle of the ceiling. As the confetti is flying, it gets sucked into the ventilation. As the last of the confetti approach the vent, the fire ball is send in the air, torching the confetti and creating a chain of fire through the ventilation. On the other side of the vent there is a __________ (depending on the theme of the movie and purpose of the protagonists, it could be a bomb, a person, a Rube Goldberg process)
If you're making a spirit movie/sketch, then you could infuse the spirit into the Snowstorm and destroy the spirit by throwing a ball of fire in it.
