Color a Sound is a sound installation by Blair Neal, that invites participants to color on a transparency and hear a corresponding sound. Sound is triggered when it passes a line, observed by MaxMSP software running in the background. Different colors control the octave of a note, blue - low, green - middle and red - high. Modes can also be changed so that blue colours trigger 808 drum sounds instead of chimes.
Choosing the right type of camera for your interactive installation is one of the most important technical choices you can make in your initial planning phases. Making the incorrect choice can really impact how well your installation reacts to its victims and it can also impact its ability to perform robustly in a large amount of environments.
