Zowie.Fractals is a plugin for the popular Eclipse IDE that lets the user explore the set of complex numbers in the Mandelbrot set. When rendered visually, these can be quite distracting, and even pretty. It features intuitive mouse usage, the ability to load and save your work as PNG files, the ability to change the number of iterations, and full editor history integration.
JCGO (pronounced as "j-c-go") translates (converts) programs written in Java into platform-independent C code that can be compiled (by third-party tools) into highly-optimized native code for the target platform. JCGO is a powerful solution that enables your desktop, server-side, embedded, mobile, and wireless Java applications to take full advantage of the underlying hardware. In addition, JCGO makes your programs, when compiled to native code, as hard to reverse engineer as if they were written in C/C++. The JCGO translator uses some optimization algorithms that allow, together with optimizations performed by a C compiler, the resulting executable code to reach better performance compared with the traditional Java implementations (based on the Just-In-Time technology). The produced executable does not contain nor require a Java Virtual Machine to execute, so its resource requirements are smaller than that required by a typical Java VM. This also simplifies the process of deployment and distribution of an application.
Onzen is a graphical front end for the CVS, SVN, HG and Git revision control systems. It represents the files managed by the RCS in a tree view with detailed information and offers functions to update, commit, add, remove, rename, revert, diff, view files, and many more functions.
Griffon is dekstop application development platform for the JVM. Inspired by Grails, it leverages the Groovy language and concepts like convention over configuration. The Swing toolkit is the default UI toolkit of choice however others may be used, principaly SWT and JavaFX. Developers may use a combination of the Groovy and Java as well as other JVM languages such as Scala, Clojure, Mirah, and Jython. It encourages the use of the MVC pattern and follows in the spirit of the Swing Application Framework (JSR 296) by defining a simple yet powerful application life cycle and event publishing mechanism.
