# Project 07 – (Curves) Futuristic Macaroni

Although a disappointingly small amount of code to show for it, this assignment was a huge challenge. Interpreting the math formulas in order to take intentional creative liberties required a lot of guess work and experimentation. I made many iterations of interactions involving different curves until I came across the epicycloid plane curve and figured I would try to work with it. This whole project for me was just about experimenting which in the end I found really rewarding, I was able to make an almost 3D feeling interactive shape with pretty streamlined code.

Notice how the columns in the spiral meld into a new column when the shape rotates beyond the rotation capacity! It’s fun to play with : ^)
