The Time Printing Machine

Interesting, because the brightness is translated into the time:
The marker stays on the paper, thus the "bleed" the marker makes corresponds to the brightness (darkness repetitively) of the corresponding pixel.
-> the longer the pen stays on the paper, the darker the pixel.

The Time Print Machine by designer Paul Ferragut uses standard felt-tip pens mounted to a device controlled by custom hardware using openFrameworks to draw pointilist representations of images.

for watching the video i recommend to turn off the sound:
