Yiannis Kranidiotis: Colour Tubes

Yiannis Kranidiotis: Colour Tubes

Onassis Cultural Center, Lobby 5

“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 colored tube with any colored cylinder and move it in front of the screen. When different colors are combined, sound, music and visuals are generated depending on various parameters like the color combination, the position or the speed of the bicolor tube-cylinder.

Single colors 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 with OpenCV library and Pure Data for the audio part. Pure Data receives all the parameters from the main software in real time via OSC protocol and generates the audio.

Yiannis Kranidiotis lives and works in Athens. His works focus on creating interactive spaces and experiences by combining sound and visuals. This involves many different fields like music, audio design, visual arts, science and coding. He has composed music for short films and theatre. His music also featured in a virtual reality reconstruction of the site of ancient Olympia by the Foundation of the Hellenic World. He has a BS in Physics from University of Patras and M.Sc. in Optics from Essex University. Website: www.kranidiotis.gr
