some more 2D spectral pathtracing

I went star gazing in a dark-sky area for the first time in decades and it was amazing, but man there are so many satellites these days. It’s almost unbelievable! As a bonus enjoy this photo of Jupiter I took with my phone. :)

This is bringing back some great vibes! liquidream.itch.io/undune2

I finally got around to refresh my website which was overdue for quite some time :) www.p1xelcoder.com

20 Years of the freedom to get weird: Brütal Legend, Stacking, The Cave, Broken Age, Headlander, Rhombus of Ruin, Psychonauts 2 and Keeper. Thank you @timoflegend.bsky.social 🧡

I drew that sign as temp art, assuming a real artist would replace it. I think they left it in to punish me. Look, it’s not easy to draw a cursive F with a mouse in Enhanced Deluxe Paint II.

After all of these years hearing about and talking about Amdahl's law, I actually I had no idea what Gene Amdahl actually looked like until today. 🤷

Everyone: You finish that trailer for Kiln? Double Fine: Sure did boss, real sexy just like you asked. Everyone: what. Kiln - Official Launch Trailer youtu.be/5y4Le4sMtMk

I built a procedural medieval island map generator using Wave Function Collapse on hex grids. 4,100 cells, 900 possible states per cell, 60fps on mobile. Wrote up the whole process with lessons learned. Links below 👇 #threejs #webgpu

You know that a project is truly done, when the nightly build is turned off.

Fly through of part of a Keeper level directly in the Unreal Engine editor. Part way through I turn on all of the game objects the player doesn't see -- it takes a lot to make games work.

i built an entire x86 CPU emulator in CSS (no javascript) you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS lyra.horse/x86css/

I had a wonderful conversation with @ronscompvids.bsky.social. Please check it out. bsky.app/profile/rons...

Here are some techniques I discovered through 14 years of shader programming:

Since it was never blessed with the big box release - I MADE ONE! Many thanks to @leepetty.bsky.social, @timoflegend.bsky.social, and @doublefine.com for a fun and funny game and Happy 15th Birthday to "Stacking"!

Stacking's 15 anniversary sharing continues! Today I'm sharing the Game Design Document I wrote for that game, all those years ago, which was part of our pre-production deliverables. You can download the PDF here: www.dropbox.com/scl/fi/8jk0e...

I'll be at #GDC2026, talking about #DOOM rendering. Hit me up if you see me around! schedule.gdconf.com/session/rip-...

Some early, abandoned concepts for Stacking to celebrate its 15 year anniversary! First is a take on a Natural History Museum where you'd eventually stack into dinosaurs to chase away the misbehaving children. Second is a Baba Yaga house, when I was thinking about having more folklore in the game

'for an estimated 4% of people, this mental imagery is weak or absent. When researchers ask them to imagine something familiar, they might have a concept of what it is, and words and associations might come to mind, but they describe their mind’s eye as dark or even blank.'

Happy 12th birthday, Broken Age Part 1! Look how adorable we all were! youtu.be/ssUFuZyu5bw?...

Happy 12th birthday, Broken Age, Part 1 ! Here's a clip from a very early previz we did while the engine was still being stood up, all done in After Effects using concept art. @doublefine.com

The RAM-price induced GPU shortage has led some folks to switch to alternatives…

Rocaille 2 vec2 p=(FC.xy*2.-r)/r.y/.3,v;for(float i,f;i++<1e1;o+=(cos(i+vec4(0,1,2,3))+1.)/6./length(v))for(v=p,f=0.;f++<9.;v+=sin(v.yx*f+i+t)/f);o=tanh(o*o);

Oh wow. It's been 11 years already? Working on Grim was a lot of fun indeed. If you wanna know more check out the mini documentary made by @2playerproductions.bsky.social www.youtube.com/watch?v=r7-6... bsky.app/profile/leep...

BEHOLD, EARLY LIGHTHOUSE VISUALS FROM KEEPER. 😍 Gamedev is so cool and weird and awesome sometimes!

Gotta keep 'em at bay you know!

a fantastic video on the relatively recently described emergent property 'branched flow'. the connection to caustic patterns on a swimming pool was a great connection to something i was familiar with. youtu.be/6aZ45RNHa6U?...

We have multiple Double Fine devs speaking at GDC this year, and if you love locomotion, James Collins is going to talk about about his gameplay programming and his work on KEEPER!

It was great chatting with @aricwilmunder.bsky.social about what it takes to build a game engine! #maniacmansion #lucasarts #scumm youtu.be/628d6-pTRzI

What a fun— and long— conversation!

Flying through a bit of the first level of Keeper, directly in UE Editor. It's really important that editor view match the game as much as possible for faster iteration.

Some very early character concepts I did for Keeper that we didn't use. These little sundial folks gradually forked into the Rocklings and more mechanical clockwork beings.

Advent of optimisations! Start now and you'll be ready for the fastest Christmas Day ever. www.youtube.com/watch?v=j-Bw...

I got sick just in time for the holidays (sigh) and as the fever prevented from sleeping last night I realized that the Christmas Carol has a lot of unfortunate sub-tones. My brain conjured this up because we recently read the book to the kids and watched the Muppet interpretation. (cont.)

Wooooooo! Keeper is one of @engadget.com's Favorite Games of 2025! 🎉🎉🎉 Always an honor to be named alongside so many other excellent games from some really talented studios. Check out the whole list, it's solid: www.engadget.com/gaming/engad...

Over the past two months, I’ve been diving into the Essence morph tech we built for Keeper - how we got here, how it works and some neat-looking results. I’m really proud of this system (and the game in general), and I hope you’ve enjoyed learning more about it. :)
