Scarf Series

Each pen plot is unique, generated from custom code that draws inspiration from a folded, patterned scarf. Each piece is original and will only be printed a single time. Many of these 11×17″ pieces take many hours to print due to the complex, intricate lines and the slow deliberate movement of the HP7475 plotter.

Stacks Series

Original algorithmic artworks generated from custom code that draw inspiration from a stack of books. Color is added by hand using water color.

Bruce is a portrait that marries algorithmically generated content with hand made strokes. Created using custom beard and braid generation applications that drive the HP7475 pen plotter mixed with hand drawn pen marks and watercolor. More information about the process available in this process breakdown post.

A combination of hand and machine made marks driven by custom software. Pen lines created using the HP7475 pen plotter.

Squids are created using a custom squid generator application I wrote in OpenFrameworks. Each squid is randomly generated and therefore unique. Squids are printed on a pen plotter and then water colored by hand. More information about the process in this post.

Peacocks are created using a custom peacock generator application written in OpenFrameworks. Each peacock is programmatically generated, and therefore unique. Peacocks are printed on a HP7475 pen plotter and then water colored by hand. Each peacock is a triptych, composed of three 11 x 17″ pieces to compose the complete work. More information about the process in this post.

Just finished a Barracuda using the HP7475 pen plotter, some custom code and watercolor. I love that the output from my application will ultimately result in physical pen marks on a piece of watercolor paper. Available for purchase

Kinected Portraits – Process

This post describes the process involved for the Kinected Portrait Series.

A custom OpenFrameworks application captured depth information using the Microsoft Kinect. The depth information was calibrated to a color image that was also captured by the kinect. Below is the raw color and depth information.

Kinect Depth Data










A series of meshes were generated with incremental triangle size  from 1 Р19. Below demonstrates the difference in spacing between the different generated meshes, 1 being the tightest and 19 being the loosest.


Various mesh sizes were chosen that allow smooth transitions between tighter meshes and looser meshes. Level 2, 4 and 8 were used to create a composite.

meshes 2 - 4 - 8

Mesh sizes 2, 4 and 8 from left to right.

The meshes were placed onto the captured color image in photoshop. The tighter meshes denoted the darker areas and the looser ones were utilized for the lighter areas, creating a ‘mesh hatching’ style. Originally the OpenFrameworks application algorithmically¬†blended the meshes based on the lightness of the image, but the process by hand provided a much more pleasing result.

Concept Execution

I’ve had this idea in my head for a long time and I finally acted on it. I drew this with watercolor and ball point pen and finished it with a touch of code. I wrote software to create the triangles behind the mouse, then printed it out onto a sheet of paper and then traced the triangles onto the original watercolor drawing.

Watercolor + Ball Point Pen Drawings

When I was off for Thanksgiving break, I could not look at the screen anymore. So I decided to do some drawings. I already gave two of them away without taking proper pictures. But I still have one that I was able to scan.

I was able to scan this one.
