TL;DR
RHEO launches a web-based version that runs instantly in a browser tab, offering a private, offline, and immersive fluid simulation experience. It emphasizes ease of access, calm, and creative play, expanding RHEO’s reach beyond hardware platforms.
RHEO’s web version has launched, offering an instant, privacy-focused fluid simulation accessible directly in a browser tab. This development makes RHEO’s calming, creative experience available without downloads, sign-ups, or data sharing, broadening its accessibility and emphasizing its core qualities of simplicity and privacy.
The web version of RHEO is designed to load within a second, requiring no sign-up or data transfer. It runs entirely offline, with all assets self-hosted, ensuring user privacy and dependability. The interface is minimal, focusing on immediate interaction: users can stir, breathe, and experiment with fluid simulations effortlessly.
Special features include Breath Mode, which guides users through breathing exercises by expanding and contracting the fluid in sync with inhalation and exhalation, customizable by pattern and duration. It also offers a Lab Notebook that tracks progress and unlocks hidden presets, encouraging prolonged engagement without nagging or complexity. Users can record and share sessions via links, creating a persistent, shareable experience that can be embedded as ambient displays or used in streaming contexts.
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.

It feels real because, underneath, it is.
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.
