Here are some portraits of friends and family I’ve made over the past few months. I love seeing people through this strange lens. Originally I imagined this system as something that would stand on its own in a gallery, automatically painting whoever stopped by. But there’s something special about the way people react in real time as the machine paints their portrait. There’s a feedback loop between subject, painter, and machine. So now I’m working on making the system more interactive, so people can see what’s going on inside the black box, and I can play the controls like a musical instrument.

COGGRAPH 2024

Here’s something new! A group of researchers from MIT, Stanford, Cambridge and UW Madison have put together a new interdisciplinary workshop “at the interface between cognitive science 🧠 and computer graphics 🫖“, aptly named COGGRAPH. I’ll be on a panel about non-photorealistic rendering, next Tuesday, July 16th, at 11am Pacific (2pm ET). It’s virtual, free, and open to the public. If you’re interested, you can sign up here to see it!
The real Chuck Close

Chuck Close, “Fred/Diptych”, 2017-2018, oil on canvas, 36″ x 30″.
I was stunned to see this series of Chuck Close portraits painted in an almost watercolor style.
“These full-color portraits and self-portraits employ a palette of only three colors: red, yellow and blue. Layering transparent glazes of paint, Close created an effect of abstract likeness entirely different from that of his previous work. The complex color relationships that unfold in these paintings are visible at the bleeding edges of each square within the grid, where the ragged ends of each individual color are visible.”

Chuck Close, “Michael Ovitz (Unfinished),” 2020-2021, oil on canvas, 72-1/2” × 61-1/2” × 2.”
When I started working on my “Big Wet Pixels” homage, I had no idea that the artist himself had spent the last few years of his life painting this way. Seeing these paintings now is bittersweet. It would have been wonderful to see what he would have done next had he lived long enough. But it’s also encouraging to see how many different interpretations are possible in this space. And that makes me want to keep exploring it.
The paintings will be on exhibit at the Pace Gallery in New York, from Feb 23 – Apr 13, 2024.
Big Wet Pixels 10: Debug View
I’m midway through a (major, long overdue) overhaul of the fluid transport layer of my watercolor simulation. Made some good progress over the weekend. But more importantly: I made lots of new bugs. Glorious, unrepentant, face-eating bugs. I almost don’t have the heart to squash them.

Continuing to explore the parameter space of this watercolor simulation. Enjoying the contrast between natural and artificial, accidental and planned. Really enjoying what’s starting to happen with color. Finding bugs, fixing bugs, creating new bugs. This is getting close to the point where I’d use it to paint someone’s portrait.

Refinement, and wandering, and more refinement. Taking control, and losing it.
Tonight’s effort was less about pigment, and more about paper and water.
Big Wet Pixels 7
Some refinements on the Chuck Close homage, and then a left turn into something very different. The bugs in my code are a source of unending joy and frustration. Someday, maybe, I’ll fix them, but where’s the fun in that?
Big Wet Pixels 6
New today: exploring making each pixel smarter, with more thoughtful brushstroke planning. Starting to get excited about the shapes and textures that emerge. (In case it’s not obvious, I’m reaching for a Chuck Close vibe here. But his work has all kinds of depth to it, I’m barely scratching the surface as of yet.) Also, I’ve added some new types of randomized color palettes, including interference pigments on dark paper. So many happy accidents. I don’t think I’ll ever get bored of this.

Bigger, wetter, more pixelated! Playing with different strategies for sub-pixel brushstroke planning. There are so many possibilities…Big Wet Pixels 4

Continuing to explore grids of big wet pixels. This one could even be considered to fit today’s Genuary prompt, “8×8”, if you squint at it. I’m getting to the point with Unity and C# where it’s starting to feel less like work, and more like play. More to come soon.
