To celebrate Keeper's first birthday (they grow up so fast) here is a juicy fractal morph we added for the Psychedelic Mode. :)

We’re celebrating KEEPER’s 1st birthday today! It was Oct 17, but the Unknowable experiences inexplicable time shifts now and again. 😉 We think it’s pretty special, and if you haven’t played, it’s a meditative journey with light puzzles to enjoy. https://doublefine.com/keeper

Something I've wanted to write up for a while, this is how I wish I'd learned spherical harmonics: andrew-helmer.github.io/demystifying...

In just TWO DAYS, the bus leaves the depot. See you Oct 14 for the launch of THANK YOU BUS DRIVER!  Until then, please enjoy our little launch trailer and get your slapping hand ready~ 🚌😉 https://doublefine.com/tybd

We are ONE WEEK from the launch of THANK YOU BUS DRIVER, and we're thrilled to announce it will be available for 💥$4.99 USD💥when it hits Steam on October 14. That's less than a roundtrip bus pass! 🥳 Help support our studio by wishlisting TYBD today: https://s.team/a/5067360

Little clip from an old prototype from 2019. Some of these elements would find their way into Keeper.

Oh man @ronscompvids.bsky.social talked LucasArts programming royalty EJ?! Nice!!! www.youtube.com/watch?v=3ytl...

Only 18 hours left to back this crazy thing! 18 hours left to bet on which prototype we polish up and ship! 18 hours to get more tahirts!! www.kickstarter.com/projects/dou...

hi friends I'm very excited to announce Halfspace, my experimental cross-platform IDE for solid modeling with distance fields! This has been in progress since midway through last year, and it's finally "done enough" to make it more public.

Not a week goes by when I don't miss Idle Thumbs.

Distorting space with sine functions #math

We are on fire at the moment!

I am SO EXCITED that Keeper is out on PS5 now! We've also added a new Psychedelic Mode to all platforms. And a permanent price drop! Check out this new trailer we made (some spoilers, but hey, it's been out for almost a year!). www.youtube.com/watch?v=Yzc5...

You know we thought Keeper just wasn’t weird enough and we HAD to do something about that!!! :)

WE DID IT! 🎉🎉🥳 Fully funded in just over 72 hours! Your support means so much to us, thank you to everyone who got us over the finish line 🥹🧡 But we're not done yet! There's an entire game jam to be had, and some amazing new stretch goals coming to the campaign. Stay tuned!

I am SUPER excited to announce that I'll be in Breda this year to present Keeper's morph tech at the Graphics Programming Conference. graphicsprogrammingconference.com

I'm sticking with the space theme for my AF pitches! :) youtu.be/KsIER5KY32g

Crazy that everyone is so hyped about a top-down urban driving game.

Confirming: When you buy a DF game now, you support us directly!

🚨 AMNESIA FORTNIGHT IS BACK, BABYYYYYYY 😎 In 10 days, we're gonna put on the best damn game jam the world has ever seen, and we need YOUR help to keep our indie dreams alive! Get notified when we launch on Aug 31:

Designing fixed wing flight in Keeper was a challenge the devs were certainly up to. Check out this clip from the GDC 2026 session "Fixed Wing Flight in 'Keeper' Pathfinding, Locomotion, and Animation of a Bird Companion" and then watch the whole thing only on GDC Vault! https://gdcvault.com/

What if your desktop looked like this?

Software engineering these days: someone is writing something to memory somewhere at some point.

Spent a few months working directly on this title when I moved over to ATG, very happy to see the positive reaction! youtu.be/YZvwxeXO6yY?...

17 years? This can't be true! It feels like yesterday. I still can't believe that I was able to bring my childhood to another generation! :)

We're finally bringing our powerful and user friendly CPU profiler to Linux! The beta version is now publically available, and it's free for 60 days during the open beta, so there's really no excuse not to try it out! Just download, extract, optimize. superluminal.eu/applications...

Inspired by @mmalex.bsky.social's dots experiments recently, tried to do some kind of "particle DOF" in the fluff renderer, effectively blowing out every particle's microparticles which gives a kind of uncanny effect that also melts my GPU with overdraw.

Happy 19th birthday to the German (and original) version of the Monkey Island Flash Film!! Dedeleeledeledleldlelelel!!! youtu.be/c0chgLTNNAQ?...

If you’re into the surreal adventures of walking lighthouses, Keeper is 40% off on Steam! store.steampowered.com/app/3043580/...

I recently gave a talk on parallel computing in video games at TU Dresden (my alma mater) and OvGU Magdeburg, looking at the historical evolution of parallelism in game consoles, why graphics is easy and gameplay hard to parallelize. Had a great time doing it! youtu.be/xZjKragRQjc

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
