Click your mouse to change the curve. This uses a cloud variable so that we are all creating the curve together.
For the Patterns SDS, I wanted to create an interactive pen pattern that uses cloud variables. This uses my "curve math" sprite, which I keep finding new ways to reuse :) Take a look at the comments in that sprite to learn how you can reuse it too. It uses a method called Cublic Spine Interpolation to create a curve between any points you give it. Music: "Waves" by Podington Bear
