Circles Animation

This is a project for my sound animation. I'm very proud of it because I made the sound-mix myself.
It is all made in Photoshop and After Effects. This is my first time making animation in After Effects. I am ready to dig deeper into After Effects. It's really a fun program to play with.
I'm still working on how I should end this shorts. Potentially this could go on for hours without an ending; my friend made a suggestion that I should made it into a desktop screen saver. Sounds like a good idea, but I have no idea how to do that.
