With or without music, let everyone take a moment to find their movement. Now try to keep track of eachother and follow (mirror/interpret/...) the person with the most obvious moves. Does it influence the collective movement aesthetic? Allow for taking over and handing over the lead. After a few minutes, switch to following where the least obvious, most minimal moves are happening. Does this stimulate to not just look at one, but everyone participating?
Obvious - not obvious

Intent: Following loudness of movement to keep eyes on each individual in the collective.
Drawn from the practice of Elsa Artmann.
