I have a simple wiggle in the codePen example, and I'm trying to see if I can save the position after each circle moves into it's first position and then move it around again randomly (all within the blue box). Right now when it wiggles, it returns to it's original position in-between each wiggle. Is that possible ? I looked at the 'swarm' example, but I am having a hard time making sense of the code, and I really would like to see how I can capture the position after it moves out into position
