Sets in Motion Plus 1 or 2

These are extensions of Sets in Motion in which additional people in the center column move out to the end. On a normal Sets in Motion, the first two people from the column become a couple — the first turns left and the second turns right. On Sets in Motion Plus 1, there must be a third person in the column. He turns left to stand between the other two in a line of 3. On Sets in Motion Plus 2, the third person turns left as before, and the fourth person turns right to stand between the second and third.
