I've been working on an event script based on the vaporetto (water bus) stops on the Grand Canal in Venice
 
it requires,
 
20 performers
 
20 music stands and score sheets
 
20 caving lamps (or other lamps that can be worn on the head)
 
20 red torches
 
20 green torches
 
conductor/metronome
 
 
it has not been performed but this is what is look a bit like
 
 
 
 
only with real people, in a real room and stuff
 
 
cheers,
