From a parallelogram (i.e., offset by one or more dancer positions, most commonly by 2): The dancers act as
though they were in a 2x4 formation, but work to the spots where real dancers are.
Parallelogram Acey Deucey:
If the call is one that rotates the 2x4 formation (e.g. Counter Rotate 1/4), the formation becomes offset lines,
waves, or columns (as appropriate to the call's ending formation), offset the same way the parallelogram
was. For example: Parallelogram Bend the Line:
The percentage of offset is preserved, not necessarily the footprints.
