Group: Trio or quartet. (If you are bigger group divide into trios and/or quartets)
Score:
In silence, no talking.
Make a formation of triangle (trio), or a diamond (quartet)
Keep the formation.
Who ever is the first one, is in lead. If she turns, the new person being the first (not seeing others) is in the lead.
Try different distances to each others. But try to keep the distance approximately equal between all member of trio/quartet (not so easy with diamond formation, because one of the distances is a bit longer).
Continue for at least 10 minutes.
Concentrate more on the movement with the form, rather than fixing the form and distances exactly but not moving through the space.
