This is one applet for constructing Fibonacci Squares and the Fibonacci spiral. The Fibonacci spiral is made up of quarter-circular arcs whose radii are consecutive Fibonacci numbers. [br]You can read detailed instructions under the applet, short instructions at the left side of the applet, or see video instructions by following the link below. [i]The order of steps is important.

1. Click on the Quarter Circle button.[br]2. Click on the green square to create a square under it (the color will change).[br]3. Drag the green square to align the blue point with the free end of the quarter circle.[br]4. Rotate the green square by dragging the red point. We want to align the red side of the green square with the radius of the quarter circle.[br]5. Click the Increase button until the side of the square equals the sum of the sides of the previous two squares.[br]6. Repeat the procedure from step 1.
