Choose your world

Fifteen first-person worlds built with Three.js — from a drowned city and an impossible city hidden in a tower's shadow to a glowing plankton bay, an Arctic festival under the northern lights, and a rave above Saturn. Walk in, wander off, find the parts nobody points you to.

A yacht party · Plato's city below

Atlantis

Board the Halcyon, a motor yacht anchored at sunset: walk her three decks, take the helm, raise a glass, talk to the girls upstairs, then watch the DJ's party build as the sky goes dark and the fireworks start over the coast. Then dive off the stern and sink onto the ruins: a paved avenue of robed statues and broken columns, jellyfish drifting through a fallen arch, caustics on the sand. Swim on and the city is still lit — domes with glowing windows, two colossi of Poseidon, veins of red-gold light pulsing toward a Great Dome whose door glows warm. Something inside it never stopped running.

Deep Space · Saturn

Afterglow

A flying saucer crossing deep space with a blacklight rave inside, a nebula and a spiral galaxy through the skylight. Take the helm, warp on the drop, thread Saturn's rings, then float down the tractor beam to a neon grid on an ice moon where the crowd is half alien. Then go through the portal — or fly the DJ pod through the ring gate — to a neon Blade Runner city standing on the rings: walk a rainy night market under lit umbrellas, play the arcade, drink at an aquarium bar and tip the pole dancers, change the channel in a tunnel of a thousand TVs, and float to a zero-G melodic techno party in the gap beside it.

The Shadow City

Walk a ruined courtyard as the sun moves across the sky. A tower's shadow stretches over the stone, and an impossible city waits inside its outline. Find the dark path, step into it, and unfold what the tower has been hiding.

Himalaya

Back to the Mountains

A trance festival in a glacial valley. Two stages face each other across the river — Sunrise to the north, Moonrise to the south — and a third floor hides up a switchback trail in the pines. Stay for the sunrise ceremony.

Goa · 1995

Anjuna to Vagator

A strip of the North Goa coast where the road runs out in the sand. Walk north past the Wednesday market and the fishing boats to a clifftop floor and a bowl that opens onto the beach — and something under a banyan that nobody will give you directions to. Swim out past the break. Stay for the sunset.

A new-moon night · glowing sea

Bioluminescence Bay

A cove on the darkest night of the month, where every wave breaks electric blue. Start on the lookout above the bay, walk down to sand that glitters where the water pulls back, and wade in: plankton sparks around your legs. Take a kayak out from the mangrove creek and the water lights up around the hull with every stroke, swim to the DJ raft anchored offshore, dive under it into a swarm of glowing jellyfish, then dance in the Net Cave, a tunnel of blue-lit fishing net on the dune.

Polar night · Arctic Norway

Aurora Ice Festival

The sun never rises here, only a blue-hour glow at noon. Start on the lookout above a frozen lake and watch the northern lights fold overhead, then walk down onto black ice that mirrors them. Dance at a stage cut from glowing slabs of ice, wander a market of lantern-lit log cabins, and find the red fishermen's cabins on stilts over the open fjord. Press X for the corona.

Three lands · by dragon

Westeros

Start in Winterfell, grey and snowbound at dusk, then mount the dragon. Fly to Dragonstone, where Daenerys plays the throne hall, or cross the sea to Vaes Dothrak on the night of the great feast: a horde of thousands wheeling round the fire, a lantern-lit night market, the moon on the Womb of the World, and a ring where you ride in as Khal Drogo to fight.

A vampire town · three bodies

Nightwalker

You were turned tonight. Wake on a rain-soaked brow above Hollow Falls, where four of your kind are waiting for you, and switch between bodies that see the world differently: as a human, warm and slow; as a vampire, cold, fast, hearing every heartbeat through the walls, bounding up the side of the grill and onto its roof; as a bat, flying blind on echolocation through a teal-misted forest. Find the glowing falls, and the one meadow where the clouds break and the sun makes your skin shine like cut glass.

Techno

Warehouse Rave

One building, two rooms. Down the stairs into the Underground — a near-black hardgroove basement where the rig punctuates the dark rather than lighting it — or through the concourse into the Arena, a 360° room built around a saucer hanging over the booth. A live crowd, a working DJ, and a night that runs build → peak → close.

Techno

Warehouse II

The same building, rebuilt. You spawn on the main corridor and walk straight ahead — the Underground is now a stairwell branching off a long red hall, and the Arena has a proper end stage with the saucer hanging over it. Ceilings of cold white LED battens marching away down the dark.

Desert

The Playa

A Burning Man–style desert city. Neon art installations on an open plain, mutant vehicles roaming the dust, and portals that drop you into whole other worlds — a fantasy forest, a winter rave, the void.

Municipal Baths · 1963

The Deep End

A council swimming pool, drained in 1998 and never refilled. Three flights down off the street, past the cloakroom and the bouncer, to a lit poolside deck — and below it, in the tiled basin, twelve hundred people on a floor that slopes away from you. The DJ works from the five‑metre diving platform. There is still water in the deep end, and the rig is reflected in it.

Giza Plateau

Pyramids at Night

A stage on the sand with the Great Pyramid standing behind it as the backdrop, and a fan of lasers thrown off its apex across the whole sky. Two towers of blue steel, a ring of light around the booth, and a drone swarm that writes over the desert between sets.

Elven Realm

Silverwood

A river valley deep in an old forest, on the night of a full moon. Walk north from the root-arch gate up a road lined with candles, past a hanging lounge under a banyan and a blacklight glade of neon mushrooms, to a stage carved into the stone at the foot of a waterfall.
