After making my particle system I wanted a second audio visualization so I found a tutorial for making balls that get bigger and smaller based on the music. I made those and added them to my first audio visualizer and I created a new project where I could make more changes to them. I wanted some of the balls to be movable and be affected by gravity. I was stuck trying to figure that out for a while but Mr. Polge was able to help me. At this point, I also decided to my new project set in space.
