Not quite sure what to think about this:
In 2009, artist Karen Green made “The Forgiveness Machine.” It was a strange seven-foot-long plastic apparatus that allowed people to write down whatever they wanted to forgive or be forgiven for. You put the piece of paper with your forgiveness wish in at one end and it was sucked through the machine and shredded at the other end. Voilà! Instant forgiveness. There were so many wishes submitted that the machine eventually broke down.
The machine was inspired by the mixed emotions Green felt about her late husband, the author David Foster Wallace, who had committed suicide in 2008. The machine helped her return to her art-making and channel her grief.
