TL;DR
RHEO has launched a web-based version that runs instantly in a browser tab, offering a private, accessible, and calming fluid simulation. It emphasizes simplicity, privacy, and creative exploration without downloads or sign-up.
RHEO’s web version has been released, allowing users to access a real-time, private fluid simulation directly in their browser without downloads or sign-up. This release emphasizes ease of use, privacy, and immediate calm, making it a significant development for digital wellness and generative art.
The web version of RHEO is a lightweight, browser-based application that loads in about a second and runs offline, with no data leaving the device. It offers a frictionless experience, immediately immersing users in a GPU-powered fluid simulation. The interface includes modes for calm, breathing exercises, and creative play, all accessible with minimal interaction.
Designed to be private and simple, the web app does not require sign-up, accounts, or cloud connectivity. It can be used as an ambient display, a calming tool, or a generative art piece, with options to share sessions via links or record clips. Its open, local-first architecture ensures dependability and user control, aligning with the core principles of privacy and accessibility.
Find your flow.
A real-time fluid playground that loads in a second, runs anywhere, and asks nothing of you. No sign-up, no download, no data leaving your device — just an open canvas of light that answers to every move of your hand.
The fastest break you’ll take all day.
RHEO starts moving the instant it loads — no menus, no tutorial. Within a second you’re stirring a genuine GPU fluid simulation; within a minute the day has dropped a few decibels. Zen mode hides every control and lets the canvas drift on its own. Friction-free, beautiful, and over the moment you decide it is.
The whole canvas expands as you inhale and settles as you exhale. You follow motion, not a timer — far easier to stay with. The thing you reach for before a hard meeting.
An 18-step Lab Notebook, hidden in plain play.
Stir, paint, experiment — and stumble onto hidden presets, surprise events, and an unfolding arc that turns idle play into 30–40 minutes. It reads real progress from the simulation itself, so it always knows what you’ve actually done. It holds your attention without demanding it.
Sessions that don’t evaporate.
- Share a link — the exact mood reproduces on anyone’s machine.
- Record a clip straight from the canvas.
- Pin to a gallery — keep the best moments.
- Flow of the day — derived from the date, the same for everyone today.
Point it at a screen and walk away.
- Ambient / kiosk mode from a single URL — no interface, your palette.
- Frame cap keeps the machine cool for always-on display.
- Music mode pulses to sound in the room — processed on-device.
- For a desk, a lobby, or behind a stream.

A serious engine runs under the calm surface — you never study it, you just feel it in how a fast stroke loads wide like a real brush. Depth you sense rather than study.
