The Null Device
Erratum is a new exhibition in London by the artist Jeremy Hutchison, who contacted factories in China, India, Turkey and Pakistan and commissioned them to make versions of their products with one intentional error rendering them useless:
And here is a piece about it in the Guardian:
Hutchison was inspired by allegations last year about the working conditions in Apple's Foxconn factory, including a story from one worker who said he would deliberately drop a spanner on the floor so that he could have a few seconds of rest while picking it up. "I became fascinated by this idea of an intentional human error to break the tedium of mass-production," says the artist. "I wanted to see what would happen if you commissioned this kind of intentional mistake into the smooth logic of a hyperefficient globalised machine."
