Implode & Explode

Beats 1-2: Dancers cross through the center, passing right shoulders and clashing on beat 1.
Beats 3-4: Dancers continue moving out from the set.
Beats 5-6: Dancers turn and start back in toward the center.
Beats 7-8: Dancers come back in toward the center. (Dancers are now corner-crossed from their original places.)

Repeat on beats 9-16 to get home. (The turn is a little later the second time because the dancers have less far to go.)
