‘Bit’ Installation Combines Art, Markov Chains

A Markov chain is a mathematical concept of a sequence of events, in which each future event depends only on the state of the previous events. Like most mathematical concepts, it has wide-ranging applications from gambling to the stock market, but in this case, [Jonghong Park] has applied it to art.

The installation, known simply as ‘bit’, consists of four machines. Each machine has two microswitches, which are moved around two wooden discs by a stepper motor. The microswitches read bumps on the surface of the disc as either a 0 or 1, and the two bits from the microswitches represent the machine’s “state”.

When a machine is called, the stepper motor rotates 1/240th of a revolution, and then the microswitches read the machine’s current state. Based on this state and the Markov Chain algorithm coded into the machines, a machine with the corresponding state is then called, which in turn moves, continuing the chain.

The piece is intended to reflect the idea of a deterministic universe, one in which the current state can be used to predict all future states. As an art piece, it combines its message with a visually attractive presentation of understated black metal and neatly finished wood.

We love a good art installation here at Hackaday – like this amazing snowflake install from a couple years back. Video after the break.
