General note for all:
As discussed, the basic game plan is to come up with a series of fixed ideas that will run in a particular sequence.
Then, we try to do the whole sequence (approximately 10-15 setups each lasting for the 15 seconds when the lights are green for pedestrians) a number of different times/days during the performance week.
For example: Monday 4am, Wednesday at lunchtime, Thursday at rush hour, Friday at 11pm, etc etc. That's not the schedule, just an example of the span of times of day that we should try.
In this way, we will have quite varied levels of success at achieving the "choreography".
