The Infinity Icosahedron lamp glowing in a dark room, its mirrored faces holding tunnels of light.

Light, folded into twenty mirrors.

Pre-launch: be first to know

Infinity Icosahedron

A 29 cm LED infinity-mirror lamp: twenty mirrored faces and thirty lines of light. It is coming as a DIY kit, as printable files, and as a finished lamp.

The DIY Kit: WLED preinstalled power supply included some soldering about an evening

The lamp taken apart: corner caps, edge trims, mirror panels, corner hubs and edge rails with their LED strips, floating around where the lamp stood.

Four parts make the frame.

  1. 12Corner capsFaceted covers on small magnets. Each hides a corner's screws and wiring.
  2. 30Edge trimsSnap-in strips along every edge that hold the panel edges.
  3. 20Mirror panelsHeld by the frame, not glued: they rest on a soft foam gasket, so any one can come out.
  4. 12Corner hubsEach sets five rails at the exact angle, held by five small screws from outside.
  5. 30Edge railsA deep channel holds the LED strip behind a frosted diffuser.

An ESP32 running WLED drives every LED, from the app, Home Assistant, or your music with an optional microphone.

Designed at every corner.

Close-up of a corner: the faceted black cap over its hub, with the edge trims lapping over the mirror panels.

12 corners

Screwed, not glued.

Each hub drops onto five rail tabs. Five small screws, driven from outside, pull each tab into its pointed socket, and a sloped tab roof stops a rail pulling out. A faceted cap, held by a small magnet pair, hides the screws and the wiring well beneath it, so every corner opens from outside.

An edge rail in section: the LED strip deep in its channel behind a frosted diffuser.

30 edges

A line, not dots.

Each rail hides its LEDs in a deep channel behind a slide-in frosted diffuser. With the Dense option, 15 LEDs per edge read as one continuous line of light.

Close-up of one mirrored face, with lines of light repeating into the distance.

20 faces

Twenty one-way mirrors.

Acrylic panels rest on a soft foam gasket, held at their edges by snap-in trims, so any panel can come out. Light bounces between the mirrored faces, and the tunnels run back as far as you can see.

Rainbow Flow

A universe of light.

Any colour, any mood. This is the lamp ray-traced: its 450 full-colour LEDs placed from the CAD model, reflecting between twenty one-way mirrors.

A simulation, not a recording: colour, glow and mirror depth are approximate.

From a box of parts to a room full of light.

  1. Build

    The hubs set every angle, so the frame closes true. Lay in the LEDs, slide on the diffusers, test the light, then set the mirrors. Plan on an evening; some soldering is needed.

  2. Connect

    The ESP32 arrives with WLED installed. Join it to your Wi-Fi and pick from more than a hundred effects in the free WLED app or any browser. No account, no cloud.

  3. Enjoy

    Home Assistant finds WLED on your network, so the lamp joins your scenes and automations. Add the optional microphone and the edges move with your music.

Designed around the golden ratio

  1. c. 360 BC

    The shape of water.

    In Plato's Timaeus, each classical element is built from one regular solid: earth the cube, air the octahedron, fire the tetrahedron, and water the icosahedron, the most round of them. Plato suggested this was why water flows and slips through your fingers.

  2. 1 of 5

    One of only five.

    It is one of just five Platonic solids, where every face, edge and corner is identical: 20 equilateral triangles, 30 edges and 12 corners, five triangles meeting at each. It has the most faces of the five. Euclid's Elements (Book XIII, c. 300 BC) closes with how to construct all five.

  3. 20

    Thrown for fortune.

    Twenty-sided dice inscribed with Greek letters survive from Ptolemaic and Roman Egypt, about 2,000 years ago, including one at the Metropolitan Museum of Art. The Met notes they were most likely used for divination: an ancient oracle book describes throwing lots to reach a prepared answer from the gods.

  4. 1509

    Drawn by Leonardo.

    Leonardo da Vinci drew the icosahedron for Luca Pacioli's De divina proportione ("On the Divine Proportion"), printed in Venice in 1509. Pacioli pointed out that three golden rectangles fit perfectly inside it.

  5. 1.618

    Golden at its core.

    The twelve corners sit exactly on three interlocking golden rectangles, with sides in the ratio 1 : 1.618. Our lamp is designed around these coordinates: the hubs sit at (0, ±1, ±φ) and its cyclic permutations, scaled to size.

  6. 1962

    Nature's favourite shell.

    Many viruses build their protective shells, called capsids, with icosahedral symmetry: the most efficient way to enclose a space from many identical pieces. Donald Caspar and Aaron Klug explained this in 1962, inspired by Buckminster Fuller's geodesic domes.

  7. 20th c.

    Domes and maps.

    Buckminster Fuller built his geodesic domes by subdividing the icosahedron. His Dymaxion world map unfolds the Earth onto one, with far less distortion than a flat map.

  8. Today

    Twenty faces of water, lit from within.

    In modern sacred-geometry traditions, the icosahedron is associated with water, and with flow, change and emotional depth. Now you can build one.

How hard is it to build?

If you can follow a recipe and you are comfortable with a little soldering, you can build this. The hubs set every angle, so there is no measuring or guesswork. First-time solderers will want to practise a few joints on a spare piece of strip first.

What tools do I need?

A small screwdriver and a soldering iron. The screwdriver drives the 60 small screws that hold the corners together. The iron joins the LED strips in the wiring well under each corner cap and sets the two threaded inserts in the mount hubs. Solder, flush cutters and a wire stripper make the job easier. Everything else is in the box.

How long does the build take?

Plan on an evening. Your first time through the guide will take a little longer than the next, and it is worth going slowly on the solder joints.

How is it powered?

A 5 V plug-in power supply is included, sized for the LED option you choose. WLED's built-in current limiter is set to match, so the lamp stays within what the supply can safely deliver, even on full white.

Dense or Standard LEDs?

Dense (144 LEDs per metre) gives smooth, continuous lines and the deepest-looking tunnels, which is why we recommend it. Standard (60 per metre) shows a dotted, pixel look and draws less power. Both work with every WLED effect.

Do I need an app or an account?

No account. WLED runs on the lamp itself over your local Wi-Fi (2.4 GHz). Use the free WLED app for iOS or Android, or open the lamp's page in any browser. Home Assistant users can add it with the built-in WLED integration.

Does it react to music?

Yes, with WLED's sound-reactive effects. They need a sound source: a small microphone wired to the controller, or audio sent over your network from another device. We will confirm at launch exactly what the kit includes for this.

What are the hanging kit and stand?

Both use a mount hub: a corner hub with a 1/4"-20 threaded insert, so the lamp can hang or sit on a stand. They are planned accessories, and full details come at launch.

When can I get one?

Nothing is on sale yet. Join the list and we will email you when the DIY Kit is ready. Shipping, returns and warranty details will be published before then.

When can I get the files or a finished lamp?
