A new project combining the collective talents of four French design studios literally allows you to see sound in a whole different light. Murmur is a device that allows passers-by to interact with an LED light wall, turning their voice into visible sound waves. Building a "luminous bridge between the physical and virtual worlds," it transfers sound waves towards the wall using an LED strip, displaying the movement of each spoken word.

Experts in visual, sound, and object design, participating studios Chevalvert, 2roqs, Polygraphik, and Splank utilized Raspberry Pi and open-source toolkits to create the installation, referring to it as “echo’s room” — which alludes to both the audio effect and Echo nymphs in Greek mythology.
