Margot Gersing – Project 7 Curves

(click on shapes to activate)

This project I was inspired by some of the shapes shown as examples on the project description. I thought the round shapes were really cute and I could imagine them as a pattern. I made it so that each shape you could manipulate individually by clicking on them. This way there could be more options for what you could create based on the mouse.
