The applet shown here requires that you have Java functionality turned on in your web browser. Most browsers have this feature turned on by default, but if you have trouble viewing the Java applet, you should check to make sure that this feature is on.

To use this applet, use the menus at the top to change the background color of the graphic (not very useful, but I wrote this for my Java class and it needed more interactive components) and to read text about different objects displayed in the text field. The text is color coded to the associated object in the graphic display. The buttons at the bottom control the time clock, allowing you to advance the clock or back the clock up. There are also a couple of buttons that allow you to control the step size of the clock increment button, you can increment or decrement the step size.
