I did not make any sketches for this, but here are images of some compositions I liked.

For this project, I wanted to create a simple turtle collage which interacted with the mouse and created interesting compositions with eachother with every movement of the mouse. I am pretty happy with my results, and how the tiniest movement can create a different composition and pattern.
