Overslack is a slackline simulator/game. A configurable model world containing a slackline, a slacker and ground is visualized and its time evolution is calculated while the user controls the slacker using the mouse. Just like with real slacklining there is no predefined goal, but it keeps track of the time you stand on the line.

The simulated world has only two dimensions. Although the forward direction offers many possibilities on a real slackline, it has very little to do with balancing and is quite uninteresting to simulate. Slow speeds are assumed, so the air resistance is neglected. The time evolution is calculated by applying Newtonian physics numerically as many times per second as the machine can handle.

The speed of the simulated world is configurable, making it run five times as slow as the real world makes it slow enough to be manageable and fast enough to keep the attention up. Unlike normal grass ground, the ground in the simulation is bouncy and doesnt cause injuries. It is (unfortunately) a bit unrealistic, but makes it more fun.

The simulated line behaves according to a quite simple model. An ideal spring between the lines point of equilibrium and the slackers feet makes a good approximation, but an ideal spring gives back all energy it stores, which would cause you to bounce forever without helping with your legs. To simulate some friction, it has a somewhat different spring constant depending on whether its extending or compressing. It is of course fully configurable, so anything from an ideal spring to an old, tired and non-elastic line are possible to simulate.

The slacker is controlled with the mouse. Move the mouse down to extend the legs, and move it up to crouch. Move the mouse to the right to lower your right arm and raise your left, and to the left to do the opposite. This is pretty much all you can do on a real slackline too, except that you can move more than just your arms, but thats just a question of terminology.

The slacker is infinitely fast and strong, if you move the mouse the slacker will move instantly to the new position regardless of the force and energy required.
It is possible to jump off the line and land on it again, with or without bouncing on the ground in between, but to make it simpler the slacker is moved to a perfectly balanced position whenever you press the right mouse button.

In addition to the line, slacker and some on-screen numerical physical information, vectors visualizing location (white), speed (green) and acceleration (red), both translational and rotational, are shown.

Construo project offers a simple wire frame construction toy.

Construo is a simple 2D construction programm (it is currently not a real game) for objects which consist of rods and springs and let them react on physical forces. You can currently construct buildings and objects like bridges, towers, spaceshuttles, etc. and you let them fall to ground and see seem smash and break.

Sound like fun, doesnt it =;-) The game is similar to Bridge Builder and heavily inspired from the Gamasutra article Collision Response: Bouncy, Trouncy, Fun.

Its covered under the GNU General Public License, thats means source code is availabel and you are allowed to modify it.

Penrose project is a virtual directory server. A Virtual Directory technology is a fairly new approach for centralizing and reducing the amount of directories needed without the problems of physical data migration.
Instead of creating new identity repositories, virtual directory handles identity queries on a case-by-case basis, drawing the required, authorized data (and only the required data) in real time from its native repositories around a network and presenting it to an enterprise application as needed.
Virtual Directory eases deployments of Identity management solution, reduces political fights over data ownership and changes how corporate data is being managed.

"Circus Linux!" is a clone of the Atari 2600 game "Circus Atari," produced by Atari, Inc. (which is itself a clone of an earlier arcade game named, simply "Circus").
The object is to move a teeter-totter back and forth across the screen to bounce clowns up into the air. When they reach the top, they pop rows of balloons and then fall back down.
(The gameplay is similar to the classics "Breakout" and "Arkanoid.")
Main features:
Game Modes:
- One- and two-players
- Two-player cooperative
- Barriers mode
- Bouncy balloons mode
- Clear-all mode
Graphics:
- Colorful, cartoon-like images

jjjuste is a Java/Jack port/rewrite of JustePort. It contains Java classes for streaming data to an Apple Airport Express. The project also contains a Jack client that allows the streaming to be integrated within a Jack audio flow.
The functionality of the basic client is more restricted than JustePort (only raw data at maximum volume), but the Jack integration gives more reliable playback on Linux and the structure of the code has been clarified (if you want to port JustePort to another language I suspect its easier to use jjjuste than JustePort, but I may be biased).
In case the above is not clear, jjjuste contains:
- a basic Java based client that can stream audio data to an Airport Express
- simple integration with Jack, which is an audio server for Linux.
This means that (almost) any audio source playing on Linux can be routed to the Airport (and so played on your hifi, remotely).
Usage:
- Get Jack running
- Download JJack from CVS (it is important you use the very latest CVS code - I committed a patch on 2007-07-10).
- Compile and install JJack (unpack, cd make, ant)
- Download Bouncy Castle and Apache Commons Codec jars
- Download the jar
- Start the client with
java -classpath jjjuste-1.0.jar:[other jars]
-Djava.library.path=[path to directory containing libjjack.so]
org.acooke.jjjuste.jack.FiniteJackClient [airport address]

GOIM is a full featured jabber / XMPP client with special features (extensions) for gamers. (e.g. broadcasting a notification when you join a server.. and see which games others play and join them with one click on the game icon beside their name)
GOIM uses the Eclipse Rich Client Plattform as GUI and SMACK as its jabber library.
You can also use GOIM InsideEclipse IDE.
GOIM is still in an early Beta Stage, which means it may contains bugs and misses features.
Main features:
- Send information about which game is played on which server (This is done by sending a presence with extended information. The information which game on which server will also be visible in the show part, so even people using another client (or icq/msn/..) will see what/where you are playing.
- Current supported games are: Unreal Tournament 2004, Live for Speed, Americas Army, TeamSpeak 2 (not a game, but works the same way)
- Basic Messenging and Presence
- Discover and subscribe to Jabber transports (which allows communication with icq, msn, aim, etc. users)
Enhancements:
- This release includes two new plugins - the InGame Messenger for DirectX 8 games, as well as the GameServer Browser which allows you to query HLSW server lists.
In addition there were many other fixes and enhancements:
- Usability fixes for linux and macOS (including a new chat window which does not use the Browser widget and therefore does not rely on any platform dependent features)
- Added support for jabber File Transfer
- Commands used to launch a game can now be customized
- Fixed bug when autojoining MUC rooms on connecting.
