Created bu Jonghong Park at the University of the Arts Bremen (Digital Media Program), the installation ‘bit’ represents a natural random process based on the principle of a Markov chain. Each machine consists of "information" engraved on the read head and an "event" caused by the operation of the motor. Linked together using a Markov chain algorithm, one can predict which of the four machines will move in the next turn.
The movements of these four machines are shown as a random process, but in fact they are sequence of events. Each of the four machines has its own state, which have been named ( 0,0 / 0,1 / 1,0 / 1,1 ), respectively. Each machine is equipped with a wooden read head with binary information on the surface and a microswitch to read the current state of the read head. The microswitch is connected to the stepper motors located in the center of the machine. A machine whose state is called moves the stepper motors by 1/240 of a degree. The microswitch turns on / off (1/0) along the surface of the read head each time the motor moves and calls the next machine corresponding to the state (2-Bit) of the current position of the read head. At this time, the machine corresponding to the measured state goes through the same process and calls another machine or itself.
