What Is Liquid Layers on grantkot.com and How Do I Use It?

Updated

Liquid Layers is a real-time, interactive liquid simulator that runs directly in a web browser on grantkot.com. You can open it from the site's demo listing and start playing immediately; on a phone or tablet, it is designed to work with touch input and the device accelerometer. The site also notes that a "Liquid Layers Maker" is coming soon, which will combine Liquid Layers with the creator's other physics systems (line physics, blobs, and smoke) into a combined 2D sandbox, alongside a site for sharing creations.

What Liquid Layers Is

According to the site, Liquid Layers is described as a "Real-time Interactive Liquid Simulator." It sits alongside other browser-based demos on grantkot.com, including:

  • Tutti Space Program — a space simulator built with WebAssembly (multithreading and SIMD) and WebGL
  • Pencil Physics — draw and simulate any shape, with multi-touch and pen input support
  • VoxelMash — a multiplayer voxel sandbox synchronized across visitors (a new version is in development)
  • Synthesizer — a multi-layered Web Audio synthesizer with customizable sounds

These are all interactive web demos rather than downloadable applications, so the expectation is that you run them in a modern browser.

How to Try It

  1. Open the site. Go to grantkot.com and find Liquid Layers in the demo listing.
  2. Start the demo. Launch it from its listing entry; it runs in the browser.
  3. On mobile, enable the accelerometer. The site specifically suggests trying it on a phone or tablet and enabling the accelerometer, which lets device motion affect the simulation.
  4. Interact. The demo is interactive by design; the site frames it as something to "play with," and the related Pencil Physics demo emphasizes multi-touch and pen support, indicating the creator builds for touch and stylus input.

What to expect on different devices

Device What the site indicates
Desktop browser Runs as a browser demo; no install mentioned
Phone or tablet Mobile-friendly; try it with the accelerometer enabled
Pen/stylus input Emphasized for Pencil Physics; touch-friendly design is a theme across demos

What's Coming

The site states that a Liquid Layers Maker is "coming soon." It will merge Liquid Layers with the creator's other physics systems — line physics, blobs, and smoke — into a single combined 2D sandbox, and a site for sharing creations is also being set up. Until then, Liquid Layers is available as a standalone demo.

The creator also mentions a separate project, Liquid Crystal, a 3D voxel sandbox whose demos are downloadable from the itch.io page (kotsoft.itch.io) for those with a powerful computer. That is distinct from Liquid Layers and is not part of the browser demo listing.

Practical Notes

  • No pricing or login requirements are mentioned on the site for the demos; treat access details as unconfirmed until you visit.
  • The site lists third-party libraries and licenses, and carries a 2025 copyright notice.
  • For updates, the site points to @kotsoft and @GrantKot.
