TL;DR
RHEO’s web-based version launches as a fast, private, browser-only fluid simulation tool. It offers calming breathing exercises, creative play, and ambient displays without downloads or data sharing, emphasizing simplicity and privacy.
RHEO has introduced a web-based version that runs instantly in a browser tab, offering a private, frictionless experience focused on calming, creativity, and ambient displays. This version, which requires no sign-up or download, is the original form of the app, from which its later Apple, Steam, and VR releases are derived. The launch underscores RHEO’s core philosophy of simplicity and privacy, making it accessible on any device with internet access.
The web version of RHEO loads in about a second, presenting a real-time fluid simulation that begins immediately upon opening a tab. It offers multiple modes, including a calming breathing exercise where the fluid expands and contracts in sync with inhaling and exhaling, customizable by pattern and duration. The interface is minimalist, with no onboarding or menus, emphasizing ease of use and instant relaxation.
Beyond calming, RHEO’s web app functions as a gentle game—users can stir, paint, and experiment with different presets, unlocking hidden features and creating a personal ‘Lab Notebook’ that tracks progress without requiring manual input. Sessions can be shared via links, capturing specific moods, colors, and flows, which others can reproduce on their devices. The app also supports ambient displays, streaming as generative art behind scenes or in public spaces, all processed locally on the device to ensure privacy and reliability.
Importantly, the web version is a single file, runs offline, and does not transmit data, aligning with RHEO’s commitment to privacy and permanence. It is designed to be as accessible as possible—usable anywhere, anytime, without dependency on servers or accounts—making it ideal for quick resets, creative exploration, or ambient decoration.
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.
