Light Catcher

Light & Sound Installation. Optical fibres, LEDs, Raspberry Pi and custom software.

“Light Catcher” is a dialogue between sound and light. The installation is composed of numerous optical fibres that interact with sound. Sound is the driving force, light is generating the space. An electric spark is igniting the reaction. Light is entrapped inside the optical fibres, reacting only to sound stimulus. Acting like a catcher, the installation absorbs and emits light. This results an emergent dance of light from the fibres and the reflections on the surrounding surfaces. The white light dominates the installation but shades of other colors exist to highlight an audio event, like the sounding French horn playing a minor second interval. The visitor is invited to walk around the installation and explore the different visual and audio aspects.

The project was created using C++ for designing the light choreography. The sound was generated in Pure Data along with acoustic instruments that were mixed together. In the final installation, a Raspberry Pi hidden inside, is playing the audio and controlling the LEDs using Python.

Colour Tubes: An Interactive Installation

Watch a video demonstrating “Colour Tubes” installation.

Description:

“Colour Tubes” is an interactive installation that allows us to combine colours, in the form of tubes and cylinders, and create sounds and music.  The visitor is invited to connect any coloured tube with any coloured cylinder and move it in front of the screen. When different colours are combined, sound, music and visuals are generated depending on various parameters like the colour combination, the position or the speed of the bicolor tube-cylinder. The visitors are welcome to trigger the installation using any coloured object like their own clothes.

Single colours cannot waken the installation and produce music. In this way, the participant can experiment with the diversity and the effect of composing differing elements and qualities in order to generate various results. This dualism also exists in the basic music scale that is used throughout the installation; a combination of C# major and G major (inspired by Richard Strauss’s opening theme of Salome opera) transposed in many keys, highlighting the need for combining different musical elements as well.

“Colour Tubes” is created in C++ using Cinder and OpenCV library. The audio part is designed and generated in Pure Data. Pure Data communicates with the main software in real time via OSC protocol.
