rAndom international: reflex installation - wellcome trust london 2011

'reflex' by rAndom international at wellcome trust


london-based rAndom international is currently inhabiting the darwin and mendel windows at the wellcome trust  
with their 'reflex' installation which transforms the vitrines into the 'habitat of an organism that represents itself in the form of light'.
they have sent us images of the installation, their largest to date, that is located at 215 euston road, london until april 2012.



the installation by night


consisting of hundreds of brass rods in which thousands of LEDs are arranged on small custom chips,
the installation reacts to viewers, passers-by and traffic, movement is based on programs that aim to
simulate complex natural phenomena. the swarm-like behaviour of the installation is derived from an
algorithm developed to emulate the collective decision making process employed by creatures (i.e. birds flocking, ants…)
in the natural world.





'reflex' recreates 'stigmergy', whereby random actions stimulate further behaviour that builds upon one another.
this leads to the spontaneous emergence of apparently patterned activity, allowing for error, experimentation and unpredictability,
encouraging viewers to see how they can influence the installation.

'an estimated 5000 people walk past the wellcome trust's windows every day rAndom internationl's 'reflex'
is the seventh in a series of annual design commissions for this prominent site. the window designs have always provoked
interesting reactions from passers-by. with 'reflex', the passers-by can provoke a reaction from the windows.'
