PATTERN — Turn anything you see into a kaleidoscope pattern

One photo

One photo. A whole collection.

Every pattern grows from the pixels inside one small square — the core. Slide it a little and a different world appears. All six of these came from the same dahlia.

Dahlia — The source: one photo of a dahlia. Each square marks a core.

Any style. You bring the source.

Watercolour, stained glass, citrus, coral, embroidery — the look comes from your source, the symmetry comes from PATTERN. Open any of these and it starts with exactly the same settings.

Mirror modes

Four ways to mirror. 6 to 16 segments.

Same stained-glass photo, four different geometries. Change the mode while it's running and watch the pattern rebuild itself.

Radial

The classic kaleidoscope: slices of the core mirrored around one centre, like a rose window.

Triangle

Mirrored triangles that repeat across the whole frame — a woven, tile-like surface.

Grid

The core mirrored left-right and up-down into a square repeat. Calm, textile-like rhythm.

Spiral

The slices twist as they move outward. A hypnotic vortex, best in motion.

Grid and Triangle fill the frame with a repeat; Radial and Spiral grow from one centre. Segment count sets how many slices or how dense the repeat is.

Motion

It moves. Keep the moment.

PATTERN is live: it spins, drifts through colour and follows your camera in real time. Freeze the frame you love, save it as a photo, or record a loop for Reels, TikTok and Shorts.

FAQ

Common questions

What exactly does PATTERN do?

It takes a small square from your camera or a photo — the core — and mirrors it with exact geometry into a full kaleidoscope pattern, live. Move the camera or drag the core and the pattern changes instantly.

Can I use my own photos?

Yes. In the browser, tap the photo icon at the top: use your camera, upload a photo, or pick one from the sample library. The photo is opened locally in your browser and never uploaded.

Is it really free?

Yes. On the web everything is unlocked right now, with no account and no watermark. If paid plans ever arrive, they'll be announced on this page first.

How is this different from AI pattern generators?

Nothing is generated or invented. Every pixel comes from your own source, mirrored with precise geometry, so the result is predictable and fully in your hands — you steer it by moving the camera or the core.

Can I use the patterns commercially?

Yes — what you make is yours, and we claim no rights over it. Just make sure you have the rights to the source photo (your own photos are perfect).

Which devices does it work on?

Any modern browser with WebGL2 — Chrome, Edge, Firefox and Safari, on phones and computers. There's also an Android app on Google Play.

Can I record video?

Yes, loops of up to 10 seconds in 9:16, 1:1 or 16:9. Video recording depends on your browser's support; if it isn't available, PATTERN tells you and photo capture still works.

Does it need an internet connection?

Only to load the page. The mirroring itself runs entirely on your device.

Made by a small studio

PATTERN is made by Hugo Software, the small independent studio behind the bnj.app collection of private, install-free tools and toys. No ads, no accounts — just things we'd want to use ourselves. Questions or ideas? Write to support@hugosoftware.net.
