## What is One Big Projector?

Turn any projector into a mapped light show. One Big Projector fits your video, photos, and effects to any wall, object, or stage — no complicated software, no laptop, no steep learning curve.

Design it on your iPhone, iPad, or Mac, preview it on your wall in AR, then connect a projector over USB-C or HDMI and your canvas goes full-screen and clean.

WHY PEOPLE LOVE IT
• Fit to anything — drag the corners to line your content up with a real wall, window, or prop
• Bend around curves — mesh warping wraps content over columns, arches, and rounded surfaces
• Bring your own content — photos, video, and live camera, or pick from a built-in library of effects and loops
• Effects and looks — kaleidoscope, strobe, sparkle, waves, and more, some audio-reactive to your music
• Layer it up — stack multiple surfaces and content layers for a full mapped scene
• Preview in AR — see the result on your actual wall before a projector is even connected
• Clean output — when you go live, the editor handles disappear for a pure, gig-ready projection

PERFECT FOR
• Holiday displays — Halloween and Christmas window and facade projection
• Parties and events — instant ambiance on any wall
• VJs, DJs, and stage shows — live visuals that map to the set
• Art installations and window displays
• Anyone who just wants to point a projector at something and make it look amazing

NO PROJECTOR YET? NO PROBLEM
Design your whole scene and preview it in AR on your wall today. When you are ready, any USB-C or HDMI projector works.

## Version history (last 3 releases)

### 1.1.1 — 2026-09-08

What's new in 1.1.1

• Photo Gallery: several photos drift over your wall at once, and a video can play underneath them
• Import several photos or videos from your library in one trip
• Photos now fill the shape by default, with a new Fit button on every layer to adjust
• Preview on your wall follows the show live: slideshows, videos, and content swaps update in AR
• Faster, cleaner start: a shorter welcome, a pulsing cue to your first shape, and a guided fit-tool demo
• New shapes and Box faces start empty, with dashed edges so every face is a visible target
• Tap empty canvas to deselect a layer and see the whole show
• Live camera as a layer, projected clean with no editor chrome
• Projects exported by earlier versions now import cleanly
• Fixed a crash on launch after updating from 1.1, plus many small fixes

### 1.1 — 2026-08-31

NEW IN 1.1

Four new shape tools:
• Frame — hollow rectangle with a real see-through cutout, for windows and picture frames
• Line — thick ribbon for LED strips and outlines
• Curve — smooth cubic-spline line, shaped with control handles
• Pen — draw your own freeform shape

Ten new Live Visuals, all seamless loops: Plasma Ball, Blue Sky Clouds, Disco Ball, Neon Frame, Black Hole, Matrix Grid, Pink Marble, Infinity Loops, Radar Ripples, Wavy Contours.

macOS now has full editor parity — right-click layer menus, hover tooltips, keyboard shortcuts, Option-drag fine adjust, and a resolution pill for the connected projector.

Pro adds Keep Projecting When Locked and Sharpen Upscaled Content.

AR wall preview now animates in real time. Projector output is now color-accurate. Countless polish: opaque drawer, per-layer collapse, smoother drags on Mac, faster Add Box, richer effect names.
