Blippoo Box


Turbulent Flow

“Turbulent flow, long considered a form of chaos, is now know to possess an intricate structure of vortices and eddies within other vortices and eddies… The spatial structure of turbulence, like that of any structure that is made of small copies of itself, is said to have a “fractal” nature… Like a vortex, which maintains its shape despite the fact that it is but part of a violently moving fluid, a command system in battle must form an island of stability amid the surrounding chaos, an island created by the same forces producing the turmoil around it.” (Manuel DeLanda).

I am now working for almost 10 years with Rob Hordijk’s BLIPPOO BOX, which is an audio sound generator that operates according to the principles of chaos theory. By designing the Blippoo Box, he attempted to bridge a crossover space between abstract (sonic) art, music and artistic craftsmanship. In the hands of performing musicians the Blippoo Box becomes an electronic music instrument that invites performers to improvise with the chaotic nature of the box. Despite this chaotic behavior, the produced sounds have particular characteristics that are roughly predictable and enable a performer to build a performance around a composed scheme.

“By using a nonlinear feedback system, patterns are created that exhibit chaotic properties like attractors, bifurcations, etc. Second, the filter also uses a nonlinear feedback system that can go into ranges where bifurcations occur, which results in the creation of ‘undertones’, where the period doublings create harmonic partials that are lower in frequency as the signal fed into the filter.” Rob Hordijk
