Paul Ferragut’s “Time Print Machine” using a deceptively simple combination of a felt pen, some blotting paper, and an algorithm that controls the time the felt pen can “bleed” on the paper.
The algorithm leaves the pen to bleed for a time period relative to the “grey value” of the individual pixel. It’s somewhat like how a digital black and white photograph gets created, i.e. each pixel has its own color value.
“The time print device uses blotting paper with Letraset felt-pen. The felt-pen ink bleed in the paper for a duration relative to the grey value of a pixel. Every “time stain” gradually recreates any images in a pointilist style. This device was made for my MA project more info at www.convivialtool.com” – Paul Ferragut.
