Filament @ Tyneside Cinema Launch - The Wall from Steve Holmes on Vimeo.
I recently had a project featured at the Tyneside Cinema launch in Newcastle. The above video misspells my name, but otherwise documents the work quite nicely. There’s also a nice write-up at Create Digital Motion.
The voronoi project of mine is currently having its second showing at the Cleveland State University Art Gallery. So far, I’ve come across two articles about the show: The Plain Dealer, and The Cleveland Free Times.
Harmonia _ An Interactive Visual Sound Installation
In this study, I focused on expressing music visually by using basic shapes of mathematical properties,
and I tried to make an experimental interface that organizes musical sound, chord and rhythm in a mathematical system. This project is a new way to express musical sound visually.
Harmonia came from Pythagorean principle of Harmonia believed that each element was structured by a different harmonia: earth is a cube, fire a pyramid, water an icosahedron, air a triangle. The world was not dominated by forces, but rather arranged in an orderly and structured (mathematical) way. Basically everything has a mathematical form. That principle can certainly be applied to my sound visualization’s fundamental concept.
There are two versions of Harmonia :
Version one and two are similar each other in terms of objects’ own way of creating their sounds and harmony. The only difference between version one and two is a center of the whole circle that can be represented in velocity of creating sounds.
Each object in version one has its own center in circle and this means it does not produce any change of speed. However, every objects in version two have one unchangible center in one big circle and velocity can be changed depending on their objects’ existances on x, y axis.

Symphony _ A Visual Sound Installation
Music has been one of the instinctive amusements.
Therefore, a music which doesn’t require any difficult technique, can be a foundation for the creation of brand new sound. I designed ‘Symphony’ with color, melody and other simple interactive factors as a continuous project of ‘Color Note’, my previous work.
‘Symphony’ is a sound visualization created with Reactable Fiducial. If one place a fiducial object in a frame on a screen, colored circular outline appears around the medium and automatically begins to move around the frame with making certain sounds according to the direction.
The motif of the circular form is a sound wave. The circle is made of three different layers and each layer gets its own color and sound everytime the circle hits the frame.
Eventually, the mixture of the diverse movements of the circle and the sound it makes, creates one big symphony in harmony.

*NOTE* 2/3 in I switch the output to MIDI to see how accurate the detection is, this is truely the most interesting part of the video.
Pitch detection on a polyphonic sound source. Examines a wav file and finds the notes which are being played then sends those notes to the MIDI out.
I switch the visualization to represent the spectrograph as a Pianoroll. I feel this gives more valuable information.
Still have to refine the pitch detection method as im getting a great deal of false positives. Harmonics detected as fundamentals and fundamentals filtered out as harmonics.

Berlin again. I just heard from the Amaze Festival and its small new sister event “Jump and Run”. This is a small, but seems to be a delicious event-series that connects and celebrates games and digital art. The first event will be on the 2. October 2008, featuring also a very nice music lineup, by the Bleepstreet label. They will have live-shows from Goto80, Rolemodel, STU, Computadora and others. If you live in Berlin, it’s worth checking out. More infos on Amaze or this event.
Color note (Ver.2) _ A Visual Sound Installation
Color note (Ver.2) supplemented previous work, Color note’s weeknesses like simplicity, algorithm of harmonics and variety of visual design. In the previous work, there were simple color pixels as traces of human’s movement on the screen, however, this newly version have various forms of circles, squares as well as altered simple pixels. Also, motion that creates during playing time became different from before like rotating or folding. 8 notes of previous work changed to 13 notes included semitones from lower do to higher do.
Combination of random harmonics made by human’s movement can rearrange through HD(Harmonic Defragmentation) algorithm. Some disconsonants chords automatically reorder to consonant chords like chord 5,8 in order to make sound familiar and comfortable for every people.

![[RÊV]e: tests with reversed time](http://images.vimeo.com/14/99/00/149900511/149900511_160.jpg)
tests dealing with time reversion to produce strange/bizarre situations.
this first series features a set of selected material divided in two categories: ‘test i: going to sleep, late at night’ and ‘test ii: now, waking up - before the sun rises’.

Color note _ A Visual Sound Installation
“Color note” makes sound improvisatory with simple interaction between human and sound and the collaboration between sound and color shows the human movement directly in real time. “Color note” matches the wavelength of sound and the RGB of color.
The screen looks like a graph since the width shows the speed of rhythm, and the length shows the notes and colors. It is similr to the traditional musical notes, however, there are pixels of cubes to visualize the sound instead of music paper.
The musical scale represents in length part consists of from lower do to higher do in octave 5, all of 8 notes. Each note is arrayed in “do-re-mi-fa-sol-la-si-do” order and “red to red” order.

Interactive Hats_ A Visual Sound Performance
Dance and Music are the most significant factors in a party. If one can detect human’s dancing or movement during party time, it will be a eat performance since it can create new form of visualizations and auditory results.
“Interactive Hats” detects participants’ movements by using hats and shows visual performances on the bottom of screen. Also, hats change sound’s pitch through people’s movements. If many hats mix each other, different sounds are also mixed.
There are Reactable Fiducial Objects on the top of hats and camera detects this mark in order to send data and play sound. This work is a part of “Nabi P.art.y 2007″. It made people dance taking hats and enjoy magical atmosphere.

Sound Marbles _ A Tangible Interactive Sound Work
In this work, marbles are used as a metaphor for Sound Sequencing.
Sounds vibrations of different frequencies are released by the marbles.
When different frequencies of sounds are combined at different times,
the marbles can create a new complex sounds or new sound compositions.
Wooden housing is used to obtain the feeling of an analog instrument.
There are 8 holes on the board, each representing a different note.
When a marble is placed over a hole, it releases a sound within a melody sequence.
Sound Marbles are very intuitive, allowing for the performer to easily study
new ways of creating and interacting with sound.

This is a demo of a self-powered wireless measurement device I codeveloped at work, under a Federal Railroad Administration contract. Each unit measures the brake force at each railcar brake beam and transmits the data via mesh network. The system is powered by the vibration of the railcar, which maintains a small rechargeable battery inside. In this case, the data is picked up by a laptop via USB radio dongle.
The brake beam is represented here by a small, instrumented flat beam for benchtop demo. As force is applied to the scale model, the finite-element model onscreen (generated in Solidworks and pre-cached) is updated to reflect the force distribution on the full-size beam. The graphical demo and radio interface code is written in Processing (processing.org) and interfaced to the native radio driver using JNative (jnative.sf.net).
