Draw With Your Face
Combining ‘Word With Friends’, facial recognition and Google Hangouts, your mouth becomes a mouse pointer. Put together by Aaron Meyers and OKFOCUS got the Google+ Hackathon - video below:
Welcome to Draw With Your Face, the fast-paced drawing and guessing game where your FACE is your PAINTBRUSH! Jump into a hangout with up to 9 friends, open up your mouth and say “AHHHHHHH” (the sound from your mic starts and stops your brushstrokes). You’ve got 2 minutes to get your friends to guess your word. The first player to correctly guess what you’re drawing scores (and you do to)! Share your best drawings on Google+. Are you ready to draw like you’ve never drawn before?
More info and links can be found here, and the development blog on Tumblr can be found here

Brain-Controlled Writing with Robotic Arm
After hearing about the video of a brain-controlled robotic arm that is going viral at the moment, I tried to look for an example which could involve artistic creation (such as drawing or painting). There are examples in experimental fashion, or experimental theater, where an actor can control a ‘flying harness’ with their thoughts, but sadly, no drawing (yet).
Here, though, is an example from 2011 (in fact there are many videos on the subject from this time) of a very simplistic implementation of drawing letters on a page, from AspenLab with their technological solution:
The objective is to interface and control a robotic manipulator using BCI2000 software. Additionally, a virtual simulation of this robotic manipulator will be developed. This system will be tested and evaluated online using scalp-recorded EEG and ECoG signals. This collaboration with the Mayo Clinic is supported by the National Science Foundation (NSF).

Sand Plotter (Part 2)
Found via Hack-A-Day, a project similar to the previous post that draws patterns on a surface covered with sand, using a metallic ball controlled with a magnet by computer:
[Nick] is working on a prototype of a coffee table sand plotter that draws patterns in sand a lot like a zen rock garden.
[Nick]‘s zen rock garden uses a magnet to draw a ball bearing across the sand in interesting patterns. The build uses 3D printed gears and laser cut parts to rotate the table around and move the magnet along a radius of the circle. During the first test of the prototype, the ball bearing jerked around but this problem was solved by adding a piece of foam under the sand. Power is supplied through a slip ring in the base, and the table is controlled through Bluetooth.

Seed Drawings by Clement Valla
Ongoing art series which looks like computer generative art, is actually a product of thousands of drawings by people:
Each Seed Drawing is an aggregate of many smaller drawings, all produced as copies of one another.
Over a 3 month period, thousands of individuals were solicited to copy small simple line drawings, through an online labor marketplace called Amazon Mechanical Turk. As each copy was completed, it in turn was replicated by other Mechanical Turk workers. Each drawing is produced by a single individual with no knowledge of the overall forms and structure within the larger drawing.
The iterative process of copying produces growth-like structures in which different patterns of influence and large-scale structures emerge. These larger drawing characteristics are purely the result of local interactions; beyond the writing of the algorithm, no single individual is making larger decisions for the group. -
DRAWING APPARATUS by Robert Howsare
Spirograph-like drawing machine constructed with two turntables:
The revolution of the records create drawings that serve as a markers of temporality. The drawings also speak to the idea of the editionable print through their ability to be replicated using domestic materials.
It’s truely impressive when you see it in action (and wonder why it hasn’t been done before), as you can see in the video embed below:

Piccolo
Small CNC bot, potential drawing machine for only $70. As you can see in the video below, it is capable of some interesting things:
Piccolo is a pocket-sized stand-alone CNC platform. For under $70, you will be able to assemble your personal Arduino-compatible kit for tinkering, and playing with basic CNC output. Be it plotting a quick graffiti, printing a one-off business card on the fly, or multiple Piccolos working together to create a large mural, this kit provides a platform for experimenting with 2D or 3D digital fabrication at a small scale.
We are currently refining the Piccolo prototype into an open-source design that is simple, quick to assemble, and easy to use, and is entirely composed of digitally manufactured components and inexpensive off-the-shelf hardware.
The Piccolo project includes Arduino and Processing libraries, to use Piccolo in a variety of ways such as moving autonomously or responding to sensors and data, whilst providing an accessible educational tool and a new output for Processing sketches.
Piccolo isn’t available yet, but you can be notified via their website here

AIKON Project
Sophisticated drawing machine features robotic drawing arm and camera sensor. It is called ‘Paul’ …
[the first minute demonstrates what happens initially, the real action starts afterwards]
I’ve covered the project before, but has since made much progress. From the project website:
Drawing, is the human activity we investigate in the AIKON project. It has been practiced in every civilisation for at least the last 30,000 years. The project will be using computational and robotic technologies to explore the drawing activity. In particular the research focuses on face sketching. What can explain that for a non-draughtsman it proves so difficult to draw what they perceive so clearly, while an artist is able to do so sometimes just with a few lines, in a few seconds? Furthermore, how can an artist draw with an immediately recognisable style/manner?
The main objective of our investigation is to implement a computational system capable of simulating the various important processes involved in face sketching. The ensemble of processes to be simulated, including; the visual perception the subject and the sketch, the drawing gestures, the cognitive activity: reasoning. the influence of the years of training, etc., the inter-processes information flows. It is evident that due to knowledge and technological limitations the implementation of each process will remain coarse and approximate. The system implemented is expected to draw in its own style.

Pythagoras
Developmental drawing robot sketches with pen, with open software for vectorizing images:
Pythagoras is a drawing delta robot. The goals for this robot was high speed and high precision pen work. OpenCV is used to vectorize images to send to the robot for sketching.
Current progress is on version 2.5. Drawing is successful and has high accuracy. The image processing program can tell the robot to either outline an image or shade it in.
Higher manipulator speed and accuracy using resolved rate path generation and Jacobians is in progress.
Potential further development includes using brushes instead of pens, a pen switcher for multiple colors, halftoning, and SVG support. More ambitious ideas include adding omniwheels on the legs so the bot can traverse large drawing areas.More information, images, and videos demonstrating how it works, can be found at aaronbot3000’s blog.

Sketch in 3D With Animated Lines on HTML5 Canvas
From Hakim El Hattab, the author of this creative, fun, online tool:
Remember the old cartoons where hand drawn lines appeared
to vibrate because of differences between frames?
That’s what this experiment simulates. It also adds a third
to your drawings by allowing you to rotate the canvas.Remember to hold space when you want to rotate your drawing.
There is also a gallery where your 3D sketches can be stored. Some good examples include this semi-3D world globe, the pictured above rotating mobile, or a 2D sketch of Jack Skellington.

The Murals of artist Helen Dennin (via Monsieur Bandit)
The work of Helen Dennis seems to balance between street art, photography and drawing. She is originally from the UK but now resides in The United States, in Brooklyn.
