The progress towards my final sketch

First I played around with my original idea, with the mouse dragging and then clicking to change and generally just learning the mouse commands.

 

Then I added color and outline

  

Then I played around with random color and making the ellipses bigger and brighter when clicking. 

Then I thought, hey ellipses are boring! I figured out how to make swirls using float, scalar, sin and cosine.

Then using the translate and mouse click I changed it so it swirled when you click and I also added some color.
 

Using an else command I finally figured out how to make them stay the same size.

Then I started experimenting with other shapes. The rectangles were definitely my favorite.

I really liked that a flat sharp square could create swirls and round shapes, I thought it was an interesting transformation. So then the challenge was to add sound and make it more interactive
