Secondly, in direct opposition to the above statement, is that the “printing” process is probably as close to pointillism as you can get.
According to FastCoDesign: “The Arduino-controlled Time Print Machine uses an algorithm to “paint” images — portraits, still lives, you name it — out of nothing but splotches of ink. Equipped with a felt pen and blotting paper, it works like a CNC-milling machine. Program the machine to render a digital image, and the pen starts stabbing at the paper, varying the amount of time it spends on each dot according to the gray value of the respective pixel; the more time allotted, the more the ink bleeds, and the thicker the dot.”
