Motoglyph, Interactive Installation
Digit devised and executed an interactive installation, MotoGlyph for the exclusive nightly Sunset Sessions at Miami's M3 Festival. The innovative installation and related website were developed to represent Motorola's sponsorship of the 2004 Miami Music Summit.
The installation comprised of three glass panels within the MotoGlyph unit, each possessing its own unique library of sounds. Guests were invited to create their own unique digital signature or illustration upon the wall from which the variables of the marks and strokes were translated into the author's own sound and animation.
Users were then able to go to the MotoGlyph website where they could download an MP3 of their unique ringtone to their mobile phone.

Digit developed a technology so users were could write on the walls with a custom made 'virtual spray can', the movements tracked via ultrasound. The movements were back projected onto glass panels, creating a virtual graffiti wall and the sensation of writing in 'light'. In real time the movements affect and create sounds.
The three panels each have a unique sound effect. The first changes the pitch along the Y axis (from your initial registration point) and adds layers of sound loops dependent on acceleration. The second layers a number of sounds loops together depending on acceleration. The third constructs at random a beat pattern from a number of libraries. It then plays this forwards and backwards depending on direction along the X axis. The speed of playback is connected to the acceleration so for example is the user "scribbles" back and forth you will hear a "DJ scratching" effect.
Visitors had to 'sign out' from the wall, indicating that the signature or illustration had finished for it to be stored on the database. Every autograph and scrawl was filed for the author to listen to on the spot or visit the website and download as a unique ringtone, MP3 or desktop wallpaper.

Technical Description of Motoglyph
- The user interface is a director/flash movie, which communicates via a socket connection to PD(pure data) - a sound processing application. Once a user begins a signature, the sound production and recording begins. A spray of light is produced on the screen taking the colour and distance information from the spray can.
- PD uses the messages passed from the movie to manipulate sound in real-time. The audio information is passed…
- to the 4 in 4 out sound card, which simultaneously outputs the audio to the speakers/headphones and back to its own audio inputs - required to record the soundfile…
- Once a user pauses for a predefined period of time (currently 3 seconds), the sound recording is paused, and the user has to make a decision to save their work, continue, or start again.
- The incoming audio is recorded directly from the soundcard, and the start/stop/pause process is controlled via an activeX control by the director movie.
- Once a signature is completed, a textfile is created which contains all the coordinate information for the signature, a label is printed which includes the created signature and a unique code, and a jpg is produced.
- At the end of an installation session, soundfiles are converted to mp3s (recorded as wav files), and all text files, and related media are manually uploaded to the website.
- The user takes their unique code to the website, and their signature is recreated as an animation with their accompanying audio file. The signature can be downloaded to their mobile phone as an mp3, or as a jpg wallpaper for their phone.

The Director projector plus all associated Xtras and additional Flash movies.
ActiveX control to record sound files
MP3 codec to convert sound files
