Synesthesia, to those who don’t experience it, often sounds like the most mind-blowing sensory experience possible - multiple senses being engaged, involuntarily, when the other is stimulated.

With this fantastical concept in mind, temporary architecture collective Plastique Fantastique and musician Marco Barotti paired up to create Sound of Life - a synesthetic sculpture designed around a former music pavilion in Hamm, Germany.

The structure is, in essence, an enormous temporary speaker. Attached to the roof of the build is a high-performance camera that films the sky above it, splitting what it films into six colours. These colours are reflected in the inflatable columns (with woofers attached) that hang from within, whereby each colour receives its different frequency converting its form from visual to audible, turning the structure into an enormous, sensory fuelled, speaker.

Plastique Fantastique describe it as “a composition of hue, saturation, and light. By mixing sound and architecture, the audience experience a unique oneiric reality through superimposed colours, shapes, sounds and vibrations."

We've seen a few experimental attempts at bringing synesthesia to the masses, ROY G BIV is an app from illustrator Julian Glander that turns colour into sound. The app takes colour data from your camera and converts it into modulations for an 8-note synth.
