Hi, Zach.
Thanks for the CodePen link. I'll try to get an account to that created today but here's a jsfiddle: https://jsfiddle.net/xqac2m58/
Maybe that helps illustrate what I'm trying to do a little? Simply put, I'm hoping to create a background aesthetic consisting of shapes which move in random directions upon page load and resize but have the shapes come to a slow stop at some interval after the page is done loading or done resizing. I've come close to having this with the TimeLineMax object but I'm stuck on trying to understand what I've done wrong with making the shapes exhibit fluid motion, meaning, they go for a second or two and then stop whereby that sequence of animation keeps repeating over and over.
