Liquid Layers Maker (coming soon)

Liquid Layers will be combined with my other physics systems (line physics, blobs, smoke) to create a combined 2D sandbox. I'm also setting up a site for sharing creations.


Liquid Crystal Sandbox

Originally, I was working on a 3D voxel game that would push the limits of the CPU and GPU. For this project, I focused too much on large simulations, and maybe due to the difficulties in performance optimization, other areas like interactions and UI suffered.

I'm currently focusing on the web and my most compatible simulations to build up an audience first. I am also able to iterate much more quickly with my web-based tech stack so I can try out more ideas. The web is also getting more powerful these days, with WebAssembly and WebGPU.

If you have a powerful computer and would like to test your metal, demos for Liquid Crystal are available for download on my itch.io page:
