Knock on Wood Machine


Our faith we place in technology is, at best, fragile. Neverthe- less, every day our existence relies upon its operation. When one part fails, our lives disrupted. The cause of these disrup- tions is often a small error. This tells us that the system we depend on is brittle and easily broken. Our dependence on the technical infrastructure of our lives is not based on cutting-edge technology. It is based on faith.

The “Knock On Wood Machine”employees a vibration sensor to detect the knock of the user. A feedback mechanism in the form of an oscillating motor rocks the piece of wood back and forth for a short time before announcing whether one’s luck has been changed or a jinx removed. The result can be either positive or negative. It is based on arbitrary readings of the vibration sensor.

The “Knock On Wood Machine” Is a comment on our own faith in technology when referenced to our lives. It’s arbitrary results are valuable proportionately to the user’s faith in technology. This is faith-based computing.
