Move your mouse pointer over the shapes on the left side and you'll pick one up. Then you can click with the mouse to stamp the shape in the picture area. And if you keep pressing, the shape will get bigger before it stamps! Just move the mouse over a different shape to change. Click the green flag to start. Green flag also clears the drawing.
Each shape in the left area creates a clone when you mouse over it. The clone follows the mouse and then stamps when you click on it. When you mouse over a new shape, the old clone disappears.
