change-a-bit

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.

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.

photo of the installation with a person interacting: they are close to the floor, moving a brick, and observing the screen.

about

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

low-level

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.
