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.

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]

"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
- Animated objects and background
- Nearly 70 objects on screen at once
- Fullscreen mode
- Random circus acts in the background
Sound:
- Upbeat circus-style music
- Many cartoonish sound effects
- Sound and music volume controls
Controls:
- Mouse
- Keyboard
- Joystick
- Real Atari 2600 Paddle controllers!

Glarf is the working title of a video game. It is a platformer like Mario or MegaMan or Contra, but thats not the Big Idea.

The Big Idea is user created content, radical trust, randomness, and play. Weapon crafting is a key example.

Glarf can shoot things - fireballs, bouncy globs, liquids. When Glarf consumes a powerup, the things he shoots inherit some of that powerups properties, by being selective in what you eat or throw away, you can create weapons with powerful and interesting effects.

Eventually, players will be able to modify the code that governs the behaviour of object in the game world. And theyll be able to share it safely with other players. But for now were just working on getting a first level done that serves as a tutorial and is still fun.
