Replace the sphere in Checkers3D by a downward-pointing pencil shape, consisting of a cylinder, with a downward pointing cone at its bottom.
Hint: look at the Cone and Cylinder classes in the Java 3D documentation.
The point of the cone should be touching the floor, and the cylinder should be on top of the cone. The cone should be light gray, and the cylinder red. Do not change the colours of the checkboard floor.
Include a small screen shot of the application showing the pencil in your report.
Explain in words what you have done.
