american design duo nervous system (jessica rosenkrantz and jesse louis-rosenberg) has a new collection of lamps
and porcelain pieces entitled 'reaction', which combine nature, science and technology, through new 3D printing
materials and interactive media.

'reaction' is based on a chemical patterning system called 'reaction-diffusion' which describes a hypothesized
mechanism for the synthesis of the diverse patterning seen on animals ranging from zebra stripes and giraffe spots
to the complex coloring of tropical fish. reaction-diffusion models substances that are diffusing , or spreading;
these substances also react with each other to create new substances. the collection of pieces employs a computer
simulation of this process to generate forms which were at once abstract and organic, reminding us of the patterns
we see throughout the natural world. the 'reaction' line features slip-cast ceramic housewares and 3D printed lamps.



'seed #1 lamp'


the 'seed #1' lamp plays with the reaction-diffusion process at varying scales, producing an organic effect.
the surface is a result of layering reaction patterns at a micro and macro scale. the larger scale pattern creates the
overall topography of the lamp, while the smaller scale modulates the surface thickness to reveal a cellular texture when lit.
the patterns of 'seed #1' at both scales, are cellular, however the surface is punctured only according to the disposition
of the smaller scale. for this particular finish, nervous system was influenced by microscopic images of seeds where both
the overall shape of the seed and the cells of which it is composed are still visible.

'seed #2 lamp'


in this version of the 'seed' lamp, the macro and micro scale patterns each have a distinct character,
interacting to create a pattern of perforations limited to the valleys of its luminous landscape.

to produce the forms of the seed lamps, nervous system created the simulations and designs in processing an
open source programming environment:

'spiral lamp'


the 'spiral lamp' is a 7" pendant lamp covered by ridges and valleys that transmit different amounts of light
when illuminated. they furnish a distinct pattern whether the lamp is on or off. the light's form is created through
a simulation process in which two chemicals diffuse across a surface and react with one another to form stable patterns.
this process can be used to explain the intricate patterns found on the skin of many types of animals from the spots
of leopards to the radiating stripes of angelfish. growing a pattern with different parameters can dramatically produce
different results. nervous system orchestrated a pattern that twists towards the base of the lamp where it terminates
into a gentle spiral. lines diverge and converge along the contours of the sphere, blanketing the surface in many
deep grooves, recalling the forms of sand dunes and hard corals.

lamp concept drawings and renderings


reaction-diffusion is one of the most canonical examples of complex, emergent behavior from a simple set of rules.
it models a set of substances that are diffusing or spreading. these substances react with one another,
creating new substances. the process has been suggested as a model for a diverse set of biological phenomena.

nervous system is also currently working in collaboration with viridis3d, a company developing a new ceramic
material for 3D printing. thus far they have created a vase design and prototype pieces of porcelain dinnerware
experimenting with this technology.





the dinnerware series features surface designs of intricate embossed reaction patterns.

pieces of the 'reaction collection' are currently on show at rare device in san francisco until october 10th, 2010.
