Purple is a series that I just made up where I mess around with math and pen and all that big boy stuff. You guessed it, I will be using the color purple a lot. The engine used to create this is 100% pen, all in one sprite.
sine is the the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse. It is often used to create ellipses(ovals).
