Javalution
Third-party products that extend the Java language or migrate legacy source code to Java (resulting in software that is part Java and part non-Java) contribute to Java's evolution—or Javalution (my terminology). This installment of Java Fun and Games introduces two such products: the Infiqs macro expander, which simplifies big decimal arithmetic, and the Snobol3 language interpreter, which merges Snobol3 with Java. Note: You can now build and run the applets presented in Java Fun and Games using DevSquare, an online development tool. Read the user guide available in Resources to get started.

Simulate fuzzy phenomena with particle systems
Computer graphics relies on polygon-based techniques to model and render classical geometry (cubes, cones, and other solids). The geometry of natural phenomena, such as fire, requires a different technique—particle systems. This Java Fun and Games installment introduces you to particle systems and presents particle system software with three examples that simulate explosion rings, fireworks explosions, and vapor trails.

Travel through time with Java
Time travel fascinates many people. You do not need a wormhole (or some other exotic device) to travel through time. This unusual installment of Java Fun and Games presents a simple computer-based technique for accomplishing time travel. Although almost any computer language could be used to implement this technique, Java offers two important capabilities that simplify the technique's implementation. Discover these capabilities as you get ready to visit the past or one of many possible futures. Note: You can now build and run the applets presented in Java Fun and Games using DevSquare, an online development tool. Read the user guide available in Resources to get started.

Add spice to your splash screen with animation
No doubt about it, animation is neat—what programmer hasn't thought about creating his own game? You can satisfy your creative streak by adding a little animation to your splash screen to grab your users' attentions as soon as they start your application. In this article, you'll learn how to create a dynamic splash screen in Java. The characters on the splash screen will fly in from all sides falling into place to reveal the desired image. To make the view realistic, you'll incorporate a little physics along the way.

Kaleidoscopes
Tube-based kaleidoscopes enchant people through the symmetric and colorful designs that are revealed as their tubes rotate. Many computer programs, including Java applets, have been created to reveal this symmetry. After identifying one of these applets, this installment of Java Fun and Games introduces two more kaleidoscope applets that you can play with.
