Punch Printers

Beurofriedrich is situated in the arches of a bridge, supporting a series of train rails leading into the city. This set of printers takes the vibration of the trains as an input source, each interpreting the behaviour slightly differently resulting in various punch patterns.
The punches are created by a solenoid with a sharp pin, controlled via a stamp producing various speeds of punch. In sound, this results in odd phasing and circulatory motions within the space, a sort of haze of registration..
