EDW Lynch of Laughing Squid says: "Gary Lee Mahmoud and a group of pranksters posed as panhandlers and slowly filled a New York City subway car, creating the surreal spectacle of a 'panhandler party.'"

Max Lupo's Thingiverse archive contains all the parts necessary to allow three people to slowly type one phrase over and over again on a typewriter, by operating a complex machine called "the convenient typer."

This is an apparatus designed to allow three people to conveniently type out a specific phrase: it is as it is

Each person must time their actions specifically, and operate their portion of the device with care.

This device was made to be a performance at a local art-event. Its operation is (of course) far from convenient, but it does type out the most true thing I have ever known.

The Convenient Typer

"Crash," Gary McNair's one-man Edinburgh Fringe show, asks audiences to rethink their relationship with money, and culminates with audience members feeding banknotes through an office shredder:

McNair promises a "five-step programme" to "release you from the terrors of the financial system". En route he takes in the history of monetisation, the notion of the collapse of trust in money (the bank run); and orchestrates a vigorous bidding war for an unspecified number of banknotes contained in a sealed envelope. Bids have, in the past, reached £100, although on his opening night in Edinburgh the bidding stopped at £26.50.

He also bartered with an audience member for her treasured necklace – her eventual price was a tour round Edinburgh, a bike ride, home-cooked lunch and the promise that he would come round and assemble her flat-pack furniture. Afterwards McNair said: "I wasn't expecting her to say she lived in Austria but if it's viable, yes, I will go to Austria and put up her shelves."

The climax of the show was, however, the moment when he suggested members of the audience feed their hard-earned cash through an office shredder, "as a vaccine against the disasters of the future, so that money and greed will lose their grip on you". Five did, with £10 notes as well as £5 notes returned to their owners as useless slithers of paper. (Destroying banknotes is not an offence, as commonly believed, though defacing them is.)
