This homework was very helpful for me.
It gives me time to start learning the basics of processing and to explore the extrange/amazing way  each parameter affects the program & transforms it completly. I combine exercises of basics functions of programming and playing with sketches that I found in github.
I explore how to make arrays to change parameters. Also acceleration and attraction between  circles. Some changes with brigthness, etc.
