CATkit :: build your own 1-bit synth from scratch (day1)  
by Tom Schouten, Marloes de Valk and Aymeric Mansoux  
This is the latest evolution of what was drafted a year ago and shown at piksel06. We have designed a PCB, selected some components, and designed a complete standalone 1-bit synth that can be programmed interactively via a computer running GNU/Linux, connected to the kit using a TTL-232R cable.
* A laptop with GNU/Linux and MzScheme? installed, or a PC laptop if you want to use pure:dyne. The laptop needs to have a free USB port.
* 250 NOK / 30 EUR to take home the board (not including TTL-232R cable)

CATkit :: build your own 1-bit synth from scratch (day2) Building tangible interfaces with Reactivision
by Tom Schouten, Marloes de Valk and Aymeric Mansoux by Martin Kaltenbrunner and Ross Bencina
In the two day workshop we will do the following
* solder the components to the CATkit board
* get familiar with some basic Purrr (Forth) commands
* incrementally create a custum 1-bit synth controller Purrr program
At the end of the workshop, the development cable is disconnected, and you go home with a little battery operated toy synth.
Please note that the focus of the workshop is on programming, not electronics. However, the Purrr language is very easy to learn, despite it being quite lowlevel. A little bit of programming experience might help though. The Purrr programming toolchain is based on MzScheme, and we urge you to install it before the workshop starts, or use the pure:dyne distribution provided.

ReacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers attached onto physical objects, as well as for multi-touch finger tracking. It was mainly designed as a toolkit for the rapid development of table-based tangible user interfaces (TUI) and multi-touch interactive surfaces.ReacTIVision is a standalone application, which communicates via the Open Sound Control based TUIO protocol, which was specially designed for transmitting the state of tangible objects and multi-touch control on a table surface. The framework includes a set of free example client projects for various programming environments, such as Processing, Pure Data, SuperCollider, Java, C# and C++, which serve as the basis for the easy development of tangible user interface applications.
* bring your own laptop
* if possible a webcam to be able to try out the reacTIVision software

Open video editing  
by Richard Spindler  
This workshop is centered around the Open Movie Editor (http://openmovieeditor.sourceforge.net/), and will go through a complete movie making workflow, from recording and grabbing media, to editing, and distribution through DVD and Internet.
What to bring:
* A laptop with the GNU/Linux Operating System installed. Additional Software: Open Movie Editor, dvgrab, dvdstyler, ffmpeg, etc.
* Optional: Camcorder, DigiCam with Movie Mode, Other kinds of Cameras

TOB - Transmitting Object Behaviors Arduino + PureData = VJ !
by Jo frgmnt Grys and Seamus O'Donnell by Marcos Yarza and Carlos Lopez
Experimental setup: Mini FM of transmitters and radioreceivers are positioned in a space, so that varied relations arise between the broadcasting and reception devices. Different distances of the apparatuses to each other generate interference between transmitters and receivers.
The Transmitters are fed with sound material coming from selfmade complex chaotic oscillators as well as from available radioprograms on air.
In a soldering workshop and/or presentation i would like to show how easy these circuits are built from basic digital chips, now crossing the border from predictable to chaotic pattern production

Arduino, the preferred open-source physical computing platform that is revolutionizing the interactive arts, and PureData, the preferred open-source visual programming software, meets up to create an amazing set of tools for VJ's. Pure Data (PD) is a real-time graphical programming environment for audio, video, and graphical processing. It is one of the most flexible tools available for creators working with real-time media. PD runs on Linux, OSX and Windows.
This presentation/workshop introduces participants in hardware creation, and visual programming software as PD to run visual live acts as vj or video artist do.The aim of the workshop is to learn how to create your own physical interface to manipulate videos in real time using PD
