INKY is s373.net/x's 8bit graffiti polar plotter.
INKY is a small painting bot capable of throwing ink / watery liquids.

It's controlled manually, with a joystick, or with gcode generated
from inkscape, or programmatically, with generative algorithms, etc.

INKY is developed in Portugal by S373.NET/X ART CODEX STUDIOS.




Inky's roots lay in 32-bit difference machine, an installation developped
by André Sier in 2009, where computer vision generated movement instructs
inky where to draw programatically.

at 64-bits solo exhibition, Who Gallery, Lisbon, 2011



Firmware and hardware upgraded, with example programs capable of generating
manual inky control, or gcode inky interpreters.

at Esculturas Generativas & DMZ,
Festival Cidade Preocupada, Montemor-O-Novo, 2015



Inky has many components, from firmware to hardware,
3d printed parts, servos, water pumps, water holder, etc.

Inky has been mainly developped by s373.net/x art codex studios,
and parts of the project are slowly being released open source,
as you may find below.

INKY has already helped to create the following electronic works by artist André Sier:

  > "32-bit Difference Machine" (2009-10) ;
  > "Anthemusa" (2014-15) ; 
  > "DMZ" (2015) ; 
  > "Portrait Machine" (2015) ;´
