Your real clock, moon and season
Morning light at your breakfast, dark water at night. The moon phase is calculated from the real lunar cycle, and the tide is modelled on a twice-daily cycle.
In Reefglass now
A series of living worlds
Each world follows your real clock, moon and season, so it is different every time you look. Simple at first glance. Flip to Detail when you want to know what you are seeing.
Reefglass is free to play now (v1.1 release candidate); Antglass, Dinoglass and Pondglass have working development builds, and eight more worlds have builds in the workshop.
What Glass Worlds is
Each world is one real ecosystem with real species. One shared model of time, light and weather drives everything you see, and every tool you use pokes that model rather than playing an animation.
Morning light at your breakfast, dark water at night. The moon phase is calculated from the real lunar cycle, and the tide is modelled on a twice-daily cycle.
In Reefglass now
By default you just see the world. One Detail toggle opens species cards, tide and moon readouts and the tools.
Being refined for v1.0
Leave it running and the world looks after itself: animals feed, grow, hunt and are recycled back into it. Predation is real but never gory.
Planned
A window you can play with, a live wallpaper behind your desktop icons, and a pre-rendered loop for your Mac lock screen.

The worlds
One engine, four very different places. Each world has its own page, palette and pace.

Kerama Islands, Okinawa
An Indo-Pacific coral reef in sunlit shallow water. Feed it, stir the current, kick up silt, wipe the glass, then dive in.

Lasius niger · a UK garden
A black garden ant colony digging its own nest in a block of real soil. Slice through it to see the tunnels, the brood and who is doing which job.

In development · build 0.5
Jehol Biota · Liaoning, China
A forested lakeshore from one real fossil assemblage: small feathered dinosaurs, early birds and volcanic ashfall, with colours drawn from fossil evidence where it exists.
Follow Dinoglass
In development · build 0.2
A UK garden pond
A wildlife pond cut through like a slice of cake, living through the real British year: frogspawn when it would really arrive, dragonflies climbing out at dawn, and ice in winter.
Hear when Pondglass is readyMore worlds on the same engine. These seven already have working first builds; the rest are in progress. No dates yet, and plans can change; join the waitlist to hear when each one is ready.
Where it runs
A signed, notarised Mac app that hosts every world in a normal window, with a menu-bar control. It follows later.
In development
The world runs behind your desktop icons. Today you can set Reefglass as your wallpaper with a free wallpaper app, following our set-up guide. The Mac app will build it in, with a frame-rate cap and pausing when it is hidden or on battery.
Set-up guide available
A full-screen mode that can start when your Mac is idle, and pre-rendered video loops for the lock screen. macOS does not allow a live 3D lock screen, so those are real captures from the engine.
Planned
Reefglass runs in a modern browser with WebGL2. Play it free on its own page, with no account needed.

Free to play
Play Reefglass in your browser, or download the single offline file and keep it. Antglass and Dinoglass are in development. Tell us if you would like to hear when a new world is ready.
Free · planned
Pick a tank and three to five fish on one simple screen, then watch the months pass. Detail mode shows temperature, pH, stocking load, the nitrogen cycle and each clash, with its source.
A planning guide, not a guarantee. Fish vary; always check with your local fish store and a water test. An educational simulation, not husbandry advice.

A live 3D world uses your graphics chip, so it does use power. The Mac app is being built to cap the frame rate and to pause when the world is hidden, when you are on battery and in Low Power Mode. We have not measured its power use on a range of Macs yet. We will publish a measured figure on this page before the Mac app is released.
The Mac app is still in development, so we have not set a minimum spec yet. It will be stated here, with the Macs we tested on, before the app is released. The web version needs a modern browser with WebGL2.
Yes. Reefglass is free to download as a single file that opens in your browser and works with no connection. You can also set it as your Mac desktop wallpaper with a free wallpaper app, following our set-up guide. The Glass Worlds Mac app follows later.
The worlds run on your own device. If you join the waitlist we keep your email, the worlds you ticked, a record of your consent and a hashed, day-scoped key used to stop spam; we never store your IP address. We never share or sell your address. See our privacy notice.
Each world is built from a researched species list with sources, but it is a simulation, not a scientific instrument. Fish behaviours are inspired by observed species temperaments. The moon phase is calculated from the real lunar cycle; the tide is modelled on a twice-daily cycle rather than a local tide table. Dinoglass uses only animals from one fossil assemblage, and where an animal's colour is not known from fossil evidence, we say so. Try your tank shows its source for every warning.
