a computer controlled by a string of bricks/bits and the cumulative actions of the participants.

photo of the installation: a row of nine bricks in the floor, all except two of them standing up. in the wall there's a projection of a monochromatic grid composed of different types of squares.

change-a-bit demo video (mp4, ~10MB)

presented in the itp winter show 2017.


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.

this project comes from when we started fully researching ways of making computing tangible and evident in its low-level workings.

although the original idea of the project was about showing these workings without using electronics, the process led us to implement in (electronics-based) software 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.
