imPulse

imPulse is an audiovisual instrument. An installation with led-stripes, speakers, metal pipes and contact mics as user interface. The led-stripes are arranged as a chaotic net with multiply nodes. The metal pipes are acoustic sound bodys and user interface to create light impulses that travel along the net. When an impulse reaches a node, it triggers a sound and splits up into multiply impulses corresponding to the system behaviour. Topic for 35C3 lab is to play with the system rules and add attributes to the traveling agents(light impulses).

rules

create a new impulse when a tube is hit at the beginning of its coresponding led srtipe
the impulse travels along the stripe. split up into three impulses, when a node - crossing of two led stripes is reached
play the corresponding note when a node is reached by an impulse
