Day 3!

Messed around with some of my colored pens and some nicer paper courtesy of @janelastname!

The last pic is a logic error that looked rad. It would destroy any pen and paper I tried to print it on, so it is presented only in screenshot form.

(reposting because I forgot I can set things to be federated)


Day 4 on the pen plotter!

A circular maze, overlaid a few times.

Possibly headache inducing.

I'm also trying out documenting everything in a git repo:


day 5 on the pen plotter!

Everybody gets to do some sine wave shapes on the plotter, right? They're so satisfying!

Day 7 of on the plotter!

Messing with line thickness. I keep filling out the page when I should really leave more white space.

It's hard making the transition from my demo display on the screen to how it'll look on an actual page!

Day 8 of on the plotter!

I got about 3 hours into a different plot before realizing that I hated it so I simplified it and got this.

Noise patterns look so good on the plotter. It feels like cheating!

Day 9 of on the plotter!

Obelisks made from an error I got a few days ago.

Day 10 of on the plotter!

Knot pattern with distortion and frayed edges.

There are some minor errors I'd love to fix, but this print took 4.5 hours so I don't think it's going to happen today.

Day 11 of on the plotter!

Messing around with some circle fills. I couldn't make up my mind so I tried a few prints.

This one was fun because it spits out really different compositions every time I run it.

Day 12 of on the plotter!

We got come concentric circles and they're all out of phase! Just a quick one today because I have to get ready to teach.

For whatever reason, Tuppy loves to curl up in his crate when the plotter is running. He’s pretty lukewarm on it most of the time, but I guess he likes the sound???

Day 13 of on the plotter!

Playing with noise fields again (they're so fun).

Busted out the metallic pens and the big 18"x12" paper that just about takes up the whole canvas bed.

Day 14 of on the plotter!

Variation on yesterday's noise field. Gold ink on large black paper. Feels ~fancy~

Day 15 of on the plotter!

Last night I wrote up some tools for my gcode library to help with occlusion. Today I had some fun with it by making a Thumper monster.

Day 16 of on the plotter!


The code pops out a new, solvable maze every time it's fun, which is probably overkill, but programmers gonna over-program.

Day 17 of on the plotter!

I tried to use simple particle interaction to define some blobby shapes and draw a map. It kinda works, but was overkill. Also it looks like a fried egg.

Day 18 of on the plotter!

Facts & Figures

I'm really happy with this one and may do a monochrome print later today! All of the graph values change every time the code is run.

It amuses me to come full circle with the plotter. It's a device that was initially intended to print charts and which was then coopted by artists. Now I'm using it to print charts that don't mean anything.


The single color print looks really nice as well!

Even the screenshot of my editor display (last pic) feels really charming.

Day 19 of on the plotter

Curves and noise to generate moirés.

I also added bezier curve support to my gcode library!

Day 21 of on the plotter

Two takes on some bezier shapes. Thought I would like the multicolor one more, but I think I prefer the black version.

Day 22 of on the plotter

I adore the path finding logic of pacman and I've been working with it a bit for an upcoming project that seemed ripe for plotting!

Here's the level 1 maze, extruded to be made of a few layers, with the paths of pac-man and the ghosts traced out.

The ghost logic is identical to the original with the exception of adding a 3rd dimension (a feature the original rules allow for very easily). In this version Pac-man just goes for the nearest pellet.

I feel like the trails really show off Clyde's unusual behavior.

Also, shoutout to The Pac-Man Dossier, probably the piece of technical games writing I come back to more than any other.

If you want to make a pac-man clone (and you should! It's a joy to program!) this paper is invaluable.

Day 23 of on the plotter!

Foggy Moon

I like the vibe on this one, but there are some technical aspects of it that bug me.

Day 24 of on the plotter!


Very happy with the texture from the pen starting and stopping on the long strokes.

Day 25 of on the plotter!

Some offset triangles.

Some printing errors along the top which are annoying me, but can't go wrong with a little moire

Day 27 of on the plotter!

Hard Candies

Very happy with this one! I'm always really enamored with plotter prints that seem to simultaneously have order and noise. My attempt at trying to hit something like that.

Day 28 of on the plotter!

Thorn Box

Started out working on spiral patterns but ended here.

Day 29 of on the plotter!


The print got messed up on the final color and only got halfway through, but honestly it was already getting kinda busy so I think it was a blessing.

Day 30 of on the plotter

Field Lines

Plotted this a few days ago. I like the vibe of this one, but it feels a bit muddy. I'd like to try this with some colors that contrast a bit more, but I'm still recovering from surgery and don't want to hunch over the plotter. Something to come back to.

Day 31 of on the plotter!

Fault Lines

I might be recovering from surgery, but I wasn't going to miss the last day of the month.

Coded this one up yesterday and printed it today.

I've had such a blast making these and it's been so lovely that people have reached out about wanting to own some of them. I think I'll be setting up a little shop soon!

I'm going for it! I'm creating a small store to sell plotter drawings! Big thanks to @janelastname & @mewo2 for giving me advice and helping me get setup!

Currently selling 5 of my pieces here:

The code to generate them guarantees that all prints are unique!

If there's anything in this thread that you want that's not listed there, please contact me directly at!

Also, for the fediverse folks who found this thread through , thank you for sending follow requests, but I'm pretty private on this account.

If you want to see my art, I just made a public mastodon account:

You can also follow me on twitter where I'm pretty active:

@mohini Do a film interview in it and ruin an editor's day!

@objelisks thanks! I want somebody to use it as an album cover!

@andy @objelisks i can't decide if it would go better with some experimental electronic music from the 50s or some art rock from the 70s

@andy I really like where they break out of their grid cells

@jonbro Thanks! I'm trying to get better at setting parameters that allow stuff like that to happen. The mathematician in me always wants everything to stay nicely in its box

@andy yeap - obv you need most of the stuff to stay in its box, but I think you could do like spiders georg outliers, things that just absolutely exit the rules

@jonbro Totally! That stuff always looks super nice when I let it happen.

@whoisgina Thank you! I'm convinced it can be super cool. I like all the pieces. I just feel like they don't stick together quite right in the current form.

@andy ya i LOVE the wavy grid but am curious to see different colors/more contrast/maaaybe a thinner line weight?

@andy hello just checking in to say that if u happen to revisit this one ever i will buy it!!!

@whoisgina Noted & thank you! It's on my short list! It's definitely the piece I made in October that I think has the most room for improvement! It's neat but not quite there yet.

@andy yaaaay yeah i love that wavy grid so much, feels so good on my eyeballs
