part of an ongoing series of drawing machines, françois xavier saint georges's 'roto-drawing machine 2' creates ink prints like these six shown above
in the second iteration of his 'roto-drawing machine', french canadian designer françois xavier saint georges (fxstg)
has assembled a random, automated drawing contraption that creates ink prints. this machine is outfitted with a wheel,
inked inconsistently by sponges suspended from a rotating disc above. during the process, the designer intermittently
sprays more ink (in red or black) onto the sponges of the machine, as it hops and moves along sheets of 24x36-inch paper,
to achieve some of the multi-hued effects.
fxstg tells us that he is currently in the process of developing two derivative projects, one of which on a much larger scale.
you can see the first 'roto-drawing machine', which used graphite as its medium, in the designboom original article linked here.
