Click on "Zeichnen" to draw something yourself. Then use the variables to set the colour gradient and the width of the pencil. Confirm this with any key. After that, the white circle follows the mouse pointer, with which you can draw something. Click on "Zeichnen lassen" to let the computer draw a picture consisting of several identical figures. In the variables, set the colour gradient, the corners of the figure to be drawn several times, the pen width, the side length of the edges and the number of figures. Confirm the selection with any key and watch how the work of art is created.
