Media Art Unit One - Spring 2012

Dave Hall Generative Audio Interaction 2006

Sound driven visual Motion and Media
(Physical media)
Preface and Introduction

Cymatics is the study of visible sound and vibration, typically on the surface of a plate, diaphragm or membrane.

Direct ocular viewing of vibrations involves exciting inorganic matter such as particulate matter, pastes (both magnetic and non magnetic) and liquids under the influence of sound, although recent research has extended the range of media to include organic matter and the range of viewing has been extended to include the light microscope.
The generic term for this field of science is the study of 'modal phenomena,’ named 'Cymatics' by Hans Jenny, a Swiss medical doctor and a pioneer in this field. The word 'Cymatics' derives from the Greek 'kuma' meaning 'billow' or 'wave,' to describe the periodic effects that sound and vibration has on matter.
The apparatus employed can be simple, such as a Chladni Plate (a flat brass plate excited by a violin bow) or advanced such as the CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.

This class and projects will be about the exploration of audio driven patterns and graphics with an intention to create an instalation.

Project One
Circuit Bending and Electronics
Duration 3 weeks

Each person will buy two or more battery powered electronic
audio devices. (Must be battery powered). One will be a
speak and spell machine the other will be up to you.

Week One – Introduction
Week Two – Disassemble and initial tests
Week Three – Adding components for control and interaction.

Note. As well as buying electronic audio devices you will also need soldering irons and various other components.

Project Two
Signal Processing and Sound
Duration 3 weeks


Sound signals have been represented graphically for as long as graphics has existed. However with a computer added to the working pipeline its possible to envisage many new and unexplored visualizations of audio data.

The basis of motion graphics is often the relationship between sound and image. However as media breaks out of the confines of the screen new methods and approaches to audio data output are emerging.


We will take our sound source from the first project. Processes it digitally then output it three dimensionally via the laser cutting fabrication process.

Week One - Introduction
Week Two – Strategies for visualizing audio
Week Three – Digital laser output


Project Three
Real-time and interaction or Pre rendered
Duration 6 weeks

For the final part of our project you have two choices.

Option One- Pre Rendered Animation
Using trapcode sound keys you can use your audio signal to generate motion graphics in After Effects. The visual style should be abstract I suggest. 

Option Two- Real Time interaction
Using your sound and circuit knowledge you will hook up your device to
a computer and use the signal to modify / change an image.

Software could be Quartz composer ( for mac ) or VVVV or which ever program you choose.

David Hall Experiments in motion 2007

Space and Motion Graphics (Still)Duration 4 weeks


The beginning of motion graphics runs parallel with the history of cinema.
And the birth of both was multiple exposure photography and the “zoetrope “. Motion capture (MOCAP) is a widely used process for calculating movement. But it can also be
used to explore motion and animation (motion graphics) through a non time based delivery medium such as still images.

In this project we will explore motion and animation through the multiple exposures, or multiple imaging techniques. In any given environment or situation still motion graphics can reveal a hidden world of possibilities and beauty not visible to the naked eye.

Step One
CONCEPT AND EXPLORATION-( 1 week duration )
Develop your concept with a view to its stylistic and visual qualities as well as how this
work will be disseminated.

Step Two
DIGITAL-(1 week duration)
Experiment with concept, location and movement through a series of images.

Step Three
FINAL PRESENTATION - (1 week duration)
I expect at least 10 experimental images from each person as the final output of this project. I also expect to see a creative unusual approach the idea of still images and
Form and Time (Animation)
Duration 4 weeks

 David Hall Multiples 2009

PREFACE - Multiples

Posit 1
"The multiple manufactures originals in series.
This means that the objects are not reproductions of an original but are themselves originals. They are not simply multiplied but manifold within themselves."

According to this key statement, formulated by Daniel Spoerri and Karl Gerstner at the foundation of their Edition MAT (Multiplication d'Art Transformable) in 1959, the multiple is to be regarded as an art form in its own right.

In this unit class we will explore the concepts behind modern “Emergent “architectural and digital media procedures. We will use the concept of the genetic multiple to explore form and digital space.


Each person will develop a formal strategy digitally, to investigate structure.

Week One – Introduction
Week Two – Primary outline
Week Three – Initial experiments One.
Week Four – Initial experiments Two
Week Five – Screen cap and play blast presentation.
Week Seven – Final presentation of stage one

Note. Autodesk Maya will be a primary tool in this project. Although you do not need to be an expert in this software you should have a general knowledge of 3D applications. I will demonstrate during class Maya procedure

Rapid Prototyping for Media
Duration 7 weeks

David Hall "Sequence 34" 2007

Flow and fluid mechanics are a primary ingredient in all motion graphics and film. In fact the principles of fluid mechanics are present in almost all physical liquid or particle systems. In this project I want you to play with the concept of flow from a digital and analogue perspective. The end result of the project will be a 3 minute animation / movie, with a sound track ( can be beat driven it’s your choice ).

To find visual patterns and rhythm's in the digital and analogue world that can be refined and experimented with to produce an object that can be printed using the 3D printer in IDAS

For each person the process will be different. These personal methodologies will be discussed in class.

David Hall 3D print Process 2007
NOTE : As this is the primary part of the class you are perfectly free to specify and proceed with your own research project. The only provision is that you write a detailed brief first

Chapter One : Lo Fi Landscape

Through a process of mathematical reduction the landscape became more and refined and simplified. All the other objects in the exhibition are developed simply using a computer, then layers of complexity are added until the computational model and the physical three dimentional print look organic and natural. In other words their construction and development history is hidden within their complexity.

This project is the reverse of that process in every way. The objects are real physical forms ( topological landscape date and human anatomy ), then this data is refined back to minimal polygonal data.

As I have spent a great deal of my time in the UK as a production designer, the work owns a lot to the process of production design in that it is more of an atmospheric physical set piece rather than computer simulation. As the landscape was reduced within the computer it was then digitally fabricated to give an exact replication in the physical world. Everything in the installation is a polygon. The light emitting from the projectors (the virtual cameras in reverse) is also triangulated by virtue of projecting through a smoke layer. This makes every light ray of the animations polygonal against the physical object. In effect you have the experience of being in the triangular landscape as you are intersected by projections beams.
