This is a design maker that you can control. Click Draw and press and move the mouse. The 3 pens will revolve around the mouse, wherever it goes. Move a large distance, and a straight line will be drawn. Stay in one place and circles will be drawn. Click Edit the change the radii of the circles by moving the green squares. Enjoy and please comment! Tell me what you make! If you want to use my method to draw circles on Scratch, go ahead. If you can, please tell me so I can see your project.
