The only thing that moves more impressively fast than the dancing pens in a high-quality pen plotter, is the human supervisor of said plotter, when some rare physical fault occurs, and the mechanism starts turning your big sheet of expensive paper into a random 3D pretzel at the speed of light. It very rarely happened! and certainly, most modern equipment would have inbuilt fail-safes, but trust me, when it happened, it wasn't subtle! One of those trash-style TV shows, based around 'When Plotters Go Bad', would be - as they say - "quite the lol". Other humorous old-fashioned plotter errors included those times when human error led to half the plot being drawn directly onto the plotter's vacuum bed (e.g. sent Landscape data, while the paper was loaded Portrait). Of little consequence except shame, that one.
