Cymatist launch this week!

If you like messing around with cellular automata, you might like Ruliad! One of three different versions of Scale Space you get when you buy it: Causmonaut, Bioclast and Ruliad. I'll be making a trailer that showcases all three sometime soon. If you try ruliad out, please share your results!

Graphics update comes to Synthesist 1.1 and then to Bioclast alpha 0.3! Here's the breakdown:

Release History

1. Scale Space Causmonaut (2025- Unreal, itch.io, 1gb ~ 500mb)
   • This version is how I initially proved out the approach to viewing and navigating Scale Space. All of the primary features, visuals, etc. were hardened in this phase and if you buy Scale Space on itch, you can play the latest build (windows only). I have another release of Causmonaut partially done and I will come back to it when I can to finish it.
2. Scale Space Bioclast Alpha 0.1/0.2 (2026- webGPU, itch.io ~ 1mb)
   • The initial port from Unreal. File size was reduced from 500mb to 1mb and particle count was increased to 1m comfortably on a few-years-old GPU (4070ti).
3. Scale Space Synthesist 1.0 (2026- webGPU, open source ~ 964kb)
   • This version was built based on Bioclast 0.2 and I was able to greatly improve the UX and fix a ton of bugs. And of course, it's now open source on github as well as zenodo if you want to cite it in formal complexity science research.

Upcoming Releases

1. Scale Space Synthesist 1.1 (Very soon- 2026- webGPU, open source ~ 965kb)
   • Tons of bug fixes and UX improvements, new features + graphics update.
2. Scale Space Bioclast alpha 0.3 (Soon- 2026- webGPU, itch.io)
   • This version will contain all of the fixes I made to Synthesist and begin to move into a diverging identity. Going forward, Bioclast will use Synthesist as its CORE engine. This means that when I make updates to the core of Scale Space, I will do it on Synthesist and that will bubble up to Bioclast.
3. Scale Space Bioclast Beta 0.1+ (Mid- 2026- webGPU, itch.io)
   • Sound/music, new themes, multiplayer, holographic atlas, and many other things. This is the version of Bioclast that will begin to behave more like a rich gaming experience like Causmonaut does.
4. Scale Space Causmonaut Beta 1.9.3 (2026- Unreal, itch.io)
   • UX improvements, bug fixes, a few new features. A release for the Causmonaut fans in the audience. The unreal build has a genuinely different look and feel than the webGPU builds. This release is almost done, but I am prioritizing the cross-platform builds first (Bioclast/Synthesist).

Confusing Enough?

Good! Clear as mud. Here's a simple way to think about it:

1. Causmonut: The OG. The ancestor of everything else.
2. Synthesist: Open Source, cross-platform. The core engine going forward.
3. Bioclast: The upcoming itch releases- a layer of rich functionality/multiplayer/graphics/sound on top of Synthesist. (edit: cymatics modes too)

The important thing to know is that the core functionality for all three versions is the same and the main differences are the graphics pipeline + platform-specific features.

Thanks for supporting the project! I wouldn't be able to do this without the enthusiasm of r/ScaleSpace, so just want to take a moment to appreciate each of you!

Best,

Release Notes

• RING MODE! Demonstrated in the above images and gifs. Ring mode is awesome and really lets you do a lot of cool things you can't do with traditional cellular automata. You can also control the ring radius.
• 'Sampled' mode which was missing from 0.1- essentially it is the traditional cellular automaton grid combined with the forces in the parameters panel. It felt too important to put on the back burner and sure enough, it's a lot of fun to experiment with.
• Lot of bug fixes. I wanted to make sure I got through all of the ones I could find before I shifted gears back to the cymatics release
• UX improvements- moving things around so they're more intuitive, renamed a few things, split some things into their own panels.

I considered calling this a hotfix due to all of the tweaks, but ring mode and sampled mode are genuinely great new features worth trying and to me they justified a complete release number.

Enjoy!
