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.
