For several years now I have had a lot of interest in Motion Design.
When possible I try to find ways to incorporate this skillset into my projects, but on corporate jobs sometimes the brand doesn't align with what I want to do creatively, so I the motion graphics usually end up being a lot more reserved. Sometimes it's just fun to animate for the sake of animating and getting that creative energy out!
I found these concentric circles to be mesmerizing.
I've always loved the way repeating shapes look in 2D animation - it really draws attention to the motion and emphasizes a sort of sense of 'energy' in the movement.
