Just choose the values for the variables, then click the DRAW FRACTAL button to draw the fractal. You can then click the CHOOSE VALUES button to go back to the decision screen.
If color change mode is on, then the color of the sides will change throughout the drawing. Clicking the pause button in the top left corner will pause the drawing of the fractal. I would not recommend choosing a level of above 5 for any shape with 7 or more sides.
