Why it’s interesting
A browser-based fluid simulation made with vgpu. Hold and drag to switch pigments as you paint; colors spread with a paper-like absorption effect while the GPU runs thirty full-screen passes per frame.
The marks retain the partly uncontrollable character of real ink. Strokes push, seep, and mix with one another, halfway between drawing and watching a tiny fluid experiment.
How to try it
Open the page and drag with a mouse or finger; each stroke changes pigment. No account is required, and a browser with WebGPU support provides the best result.
Use the official page or demonstration as the current reference. Do not assume that a staged installation, limited experiment, account-gated demo, subscription feature, or physical product is available everywhere.
Requirements and sources

Pricing, access, regional availability, accounts, hardware, and service support can change, so verify them on the [first-party source](https://immense-jaguar-8615.edgespark.app/api/public/s/vgpu-ink) before trying or buying. The description stays within the documented AI role and does not treat promotional claims as independent testing.
