Ian Kaneko Project-07-Curves

Honestly I had very little idea of what I was doing or where I was going with this project. In the end I just experimented around with different equations until I found something that looked cool. The background of my project is a failed attempt at adding more complex curve. However I kind of liked the randomness that it added so I decided to keep it around. I added a cruciform on top of it which ended up having a very interesting shaped fill space. To finish it off I added a “+” to the center that would rapidly spin, making it look circular.
