THE SKY WAS NEVER THIS CLOSE.

A ceiling.
An entire
universe.

The aircraft above you. The stars beyond them.
A living window to the sky, in your own room.

01 / WHEN THE LIGHTS GO DOWN

Ordinary room.
Extraordinary
perspective.

The ceiling becomes a quiet, moving sky.
Only the light remains.

02 / EVERY FLIGHT HAS A STORY

You hear it.
You look up.
There it is.

Skylight turns the planes overhead into glowing, gliding flight paths. The plane passing over your home is the one crossing your ceiling.

EXAMPLE FLIGHT
UAL 237SFO — LAX

AIRBUS A320 6,200 FT

03 / FAR BEYOND THE FLIGHT PATH

A sky that
never stands still.

The moon, stars, planets, and satellites, worked out for your place in the world. Even the International Space Station makes an appearance.

Choose a layer. Watch the sky change.

04 / THE WHOLE IDEA, IN THREE PIECES

A little hardware.
A lot of wonder.

A Raspberry Pi runs the software. A projector points up. An optional radio listens for the planes around you.

A small USB radio hears the planes directly. No internet feed needed.

THE ACTUAL PROJECT / AFTER DARK

This is a real ceiling.

Real Skylight footage. Real planes, projected in a real room.

Build your own

BEFORE YOU LOOK UP

A few good questions.

Do I need a radio?

No. Start with the free online flight feed, or add a small USB radio to hear planes directly. The online option needs internet.

Will it work where I live?

Set your location from your phone and Skylight works out the sky above you. You can add nearby airport runways by airport code. How many planes you see depends on local traffic.

Do I need an expensive projector?

No. A 1080p projector with a built-in stand that tilts to face the ceiling works well in a dark room. The build guide has picks at a few prices.

Is the software free?

Yes. Skylight is free and open source under the MIT license. You buy the hardware. The code and help are on GitHub.

Is this page showing live flights above me?

No. This page is a 3D demo with made-up flights. The Skylight you build shows real planes and the real sky for your location.
