A graphical computer manipulated by a string of rocks and the cumulative actions of the participants

change-a-bit is an interactive installation that consists in a computer controlled by a string of rocks/bits.
The computer’s visual output is a monochromatic grid that has/is/represents a memory.
Participants can change the state of the rocks to manipulate the state of the grid, one action/instruction/rock/bit at a time.
The grid/memory/history at any point in time shows/is the result of the accumulation of the previous actions/instruction/changes; any major transformation would require many steps.
