To start, press the green flag. Then, use the buttons on the right (the erase, draw, and move button). The erase button erases the screen, the draw button is to draw the spiral, and the move button is to move your pen (the purple circle) to a random part of the screen. Use the sliders on the left side to change the color, number of sides, size, and length of the spiral.
