The Butterfly Effect

a modification of anti-freeze tag where the plot* begins by going in reverse chronological order and then the first scene (in terms of story) is replayed with a change suggested by the audience, then the plot goes forward in time until we get to the first scene again. So (scenes numbered according to chronological time): 5-4-3-2-1-suggestion interlude -1-2-3-4-5. Scenes are edited with narration of the form "XX years earlier" in the first half and "XX years later" in the second half.

*where plot is the sequence of events as the audience sees them - and story the sequence according to chronological time.
