Starting six years ago this month: "City Planning," a series of pen plots that imagines fictional city grids. This algorithm evolved over the years to include circles, waterways, and devoid areas and I continue to build upon it.

A drawing of parallel lines that form rectangles in white ink on black paper. In certain quadrants, the angle changes. It looks like a fictional city street map.

Man, these are AMAZING.

Reminds me of seeing a bunch of plotters at some kind of public convention in the very early nineties.

I thought those tabletop suckers were the coolest thing since sliced bread.

I even had a Brother plotter/typewriter when I was in 7th grade ^__^

@RL_Dane Thabks! Happy you like them.

Vintage plotters are amazing machines to watch as they scribble on paper. Was the Brother typewriter you had the Type-A-Graph? I have the Sears OEM version (the not so cleverly named Type-O-Graph). 😊

Yes, that was precisely the one, with the blue arrow keys. :D

City Planning is based on a growth algorithm. With different constraints and rules, get some different results. In this animation, the lines grow and divide rapidly in any direction. The result resembles fracturing of glass. This as well as all my pen plotter art is programmed in Python.

An animation of a line in the center getting longer, rapidly splitting into multiple lines, those lines splitting into more lines, and so on. Quickly, the screen is taken over by lines that touch but don't intersect, resembling fractured glass.

Most recently, I’ve revisited this growth algorithm to incorporate my color style. These plots imagine a city plan that stretches beyond the surface to show multiple layers. Imagine these layers as subterranean levels or perhaps different periods of time. CMY ink on 11”x25”watercolor paper. Hope you enjoy them!

Detail of the pen plot of lines touching but not intersecting with certain bounded regions hatch filled. These different colors of yellow, cyan, and magenta layer to create vibrant colors.

Another iteration of CMY City Planning. This one is hatched more densely so it’s more vibrant. 11”x15” watercolor with a HP DraftPro DXL (1989).

All of my pen plotter work is done with custom Python which generates the images and controls the vintage pen plotters for output over RS-232.

Detail (upper left) from a generative pen plot of cyan, yellow, and magenta lines whose end points touch but not intersect, with certain bounded areas hatched. The colors layer on top of one another to create vibrant colors. A large circle dominates the center-right of the image which interrupts the otherwise straight lines.
