Adjust the sliders to make a spiral. Size changes the amount of empty space inside the spiral while direction changes the direction the spiral starts in. For a math explanation, see the Notes and Credits.
This spiral generator makes a spiral using r=kθ, where k is represented by the size variable. Because the spirals were too large and didn't spiral enough, I changed the formula to r=kθ/50, which solved the problem by increasing the spiraliness of the spirals.
