I'm new to processing and still exploring, but I'm struggling to reference an effect I am trying to achieve and not sure what to search for.

I would like to create a type logo made up from dots/ellipses of various scale and colour. I initially started to explore this by drawing dots by hand in illustrator but it'd be great to explore this in Processing so I can vary the parameters. It's not really getting shapes to follow a path, but more to be contained within the shapes. Eventually I'd like to explore particles, mouse interactivity and processing.js, but this is my first stage to learning more about it. Sorry for the newbie question.

cheers
