For this project, I at first was trying to create an image more similar to a typical spirograph. However, after choosing to work with the epispiral, I liked how it almost looked like shattered glass. It reminded me of a comic strips and when an action was done there would be action bubbles. I then chose to animate it similarly to a “POW” action that could be drawn in the comics. Therefore, I overlayed the original epispiral with another with colors that could seem comic book like.
