a computer controlled by a string of bricks/bits and the cumulative actions of the participants.
presented in the itp winter show 2017.

# interaction
each brick/bit has two possible states: high or low.
the string of bricks/bits encodes an instruction for the computer: the cell in the screen that will be modified, and the visual pattern that will be assigned to it.
=> ./img/foto_change-a-bit_03.png photo of the installation with a person interacting: they are close to the floor, moving a brick, and observing the screen.
although the original idea of the project was about showing these workings without using electronics, the process led us to implement the screen and the computer vision algorithm to detect the bricks using a depth camera.
the physicality stayed: we loved the experience of having other people and us interact with this computer via rough and found bricks, close to the floor.
