TEAMS: You may work on this by yourself or in teams of two.
METHOD: We've discussed two basic approaches to Java3D games - using a lot of the built-in behaviors (like Seek does) or keeping track of objects in program variables and having a single frame update behavior (like MBall5 does). Either of these (or a mixture of the two) will be fine.
You can display score, win/lose, etc. by simply printing to System.out . If you want to do something a little extra, you could use techniques like in MBall5 to display game status using labels, etc.
HAND-IN: You should email me a copy of your .java file and your .html file (to display the applet). Be sure that your program includes comments saying who wrote it. Also, either your code or a separate file should explain what the program does and how to work it (what input is expected).
