This list contains some of the projects I'm working on in my free time. To many of these projects I'm of course not the only contributor. To avoid confusion about the degree of activity and work I spent on the different projects I've added a contribution note. The contribution note is an eventually commented percentage value which reflects my own estimation of how much my contribution makes up the project compared to the contributions of others, including active user contributions like testing feedback and bug reports. If a project is based on a predecessor, like Gridarta is based on CFJavaEditor from Crossfire and Daimonin, this is of course also taken into account.
This project list, though probably providing the best overview in terms of first screenshots and links, is neither always uptodate nor complete. There are some automatic services that provide similar project lists. Please note that these automatic services also are neither always uptodate nor complete.

IRC: #aceunit.
Contribution: 100%.
AceUnit (Advanced C and Embedded Unit): a comfortable C code unit test framework. AceUnit is JUnit 4.x style, easy, modular and flexible. AceUnit can be used in resource constraint environments, e.g. embedded software development.
URL: ↗http://cherbot.sourceforge.net/.
IRC: #cherbot.
Contribution: 95%.
CherBot is an information bot for Daimonin which probably would also work pretty well with Angelion and to less extent with Crossfire. CherBot keeps track of which players collect which items, who's been online, determines a level ranking, provides a mail system for mailing offline players, manages clans and more.
The current size of CherBot is 10653 lines of Java source code. CherBot is currently undergoing a major redesign to shorten the source, decrease the heap footprint, support multiple protocols (planned: daimonin, irc, crossfire) and database backend plus information exchange between these servers, e.g. send messages from irc to daimonin players and back.
URL: ↗http://crossfire.real-time.com/.
IRC: #crossfire.
Contribution: 0.05%.
Crossfire is a 2D MMORPG which features hack and slay, many spells (more than 150), a huge amount of maps and an elaborate skill system. It consists of a server, archetypes (object definitions), maps and scripts, sounds, a 2D client (alternative third party clients available), a classic editor written in C and a new editor written in Java (now superceded by Gridarta).
URL: ↗http://www.daimonin.com/.
IRC: #daimonin.
Contribution: 2%; head of editor development since march 2005.
Daimonin is a 2D hack and slay MMORPG in the tradition of and based on Crossfire. It consists of a server, archetypes (object definitions), maps and scripts, sounds, a 2D client and an editor (now superceded by Gridarta). A future version of Daimonin that features 3D is currently under development.
Daimonin is approx. 220000 lines of source code (client, client3d, server) and 675000 lines of data (maps, objects).
URL: ↗http://gpu.sourceforge.net/.
Contribution: 0.001%; little help with setting up the SF project and CVS repository.
An extensible framework for distributed computing on P2P grids. We support peaceful, free and open research and hope to build an internet supercomputer. We render movies, crawl the internet and improve a ~30 GHz cluster of Gnutella/Pastella clients.
URL: ↗http://gridarta.sourceforge.net/.
IRC: #gridarta.
Contribution: 25%.
Gridarta is a level / map editor for 2D MMORPGs like Angelion, Crossfire and Daimonin.
The current size of Gridarta is 82264 lines of Java source code (with some redundancy of approx. 30% because of merging the crossfire editor and the daimonin editor which were based on the same root).
I also have some personal pages about Gridarta.

JackSemmel is a drag&drop XML editor specifically designed for collating parts of several XML documents into others.
JackSemmel is not released yet. You may get a pre-release on ✉inquiry by e-mail.
URL: ↗http://japi.sourceforge.net/.
IRC: #japi.
Contribution: 95%.
JAPI is a collection of Java libraries that help with various tasks like argument parsing, i18n/l10n, creating gui applications, as well as tools that demonstrate this.
Currently JAPI is approximately 43000 lines of Java Source including demo and example source code. It is undergoing a major refactoring to split it up into several modules for different purposes. The current state of the refactoring is 70% done.
URL: ↗http://jargl.sourceforge.net/.
Contribution: 98%.
Jargl is a library for parsing command line arguments in Java. It was part of JAPI and has been extracted into a project of its own.

URL: ↗http://www.java2html.de/.
Contribution: 3%.
Java2Html converts Java (and other) source code (complete files or snippets) to HTML, RTF, TeX and XHTML with syntax highlighting. This open source Java project consists of an extendible library along with a Java application, a Java applet and many plugins in order to integrate the library into other programs.
I've contributed XHTML 1.1 output and a few bugfixes to Java2Html.
I've tried to drag this project to SourceForge, which would have made it easy for me to contribute more. Alas there already is a project registration named java2html at SourceForge. That java2html project on SourceForge was registered in 2005-04-11 but had absolutely no activity for almost two years.
Finally, ↗Java2Html now is available at SF because Markus Gebhard has published it as part of his ↗JDemo project.

Contribution: 99%.
JEduca is a clone of ↗KEduca written in Java.
JEduca is not released yet. An old version of JEduca is part of the examples that come with JAPI.
URL: ↗http://sourceforge.net/projects/jreptator.
Contribution: 100%: creation, admin.
JLinkCheck is a link checker for XHTML. JLinkCheck and JReptator currently are unmaintained, but I might start working on them again any time.
URL: ↗http://jxfire.ailesse.com/.
IRC: #jxfire.
Contribution: 0.001%.
JXFire is an MMORPG based on SGS. Currently I'm motivating the team and contributed two small patches for German l10n.
URL: ↗http://karatasi.sourceforge.net/.
IRC: #karatasi.
Contribution: 0.001%.
Flip card learning program for iPhone with a spaced learning algorithm like SuperMemo. You create your own databases and edit the cards directly on the iPhone. Supports synchronization of data with a PC through a web server, and import of Palm databases.

Contribution: 100%: creation.
MegaXSLT is an Ant task for running XSLTs in parallel, significantly speeding up XSLTs on multiprocessor machines.
Currently MegaXSLT is 2377 lines of Java Source, including an Ant Task to run GZip compression over a fileset.
MegaXSLT is not released yet. You may get a pre-release on ✉inquiry by e-mail.

URL: ↗http://sourceforge.net/projects/opacm.
Contribution: 75%: creation, admin.
OPACM was meant to become an application for Organizational profiling and competency management
. Since OPACM is somewhat left alone by its inventor and I was only the invited technical expert, this project is basically abandoned. It has never grown beyond the stage of a generic graphical JDBC client with 569 lines of Java Source.
