Koi 2.1 puts any photo behind glass

Fluted glass is everywhere right now: shower doors, café windows, half the wallpapers people post. Put a photo behind those ribs and it turns soft and wavy, like you're looking at it through a bathroom window. It looks great behind your windows and your icons.

Koi already lives in your notch. So in Koi 2.1, the notch makes these too. Pick a photo, pick a look, set it.

1. Hover the notch, open Tools and click Glass wallpaper. It opens on Aurora, one of Koi's own photos.
2. Pick a photo: Aurora, Cloudscape, Colour, Flow or Waves, or the sixth tile for one of yours. Or drop a picture on the preview.
3. Pick a recipe: Classic Flutes, Tidal, Soft Lens, Rain or Tiles.
4. Click Set as wallpaper.

It goes on every screen you have, each at its own full resolution. No blurry stretched picture on the big monitor.

• Grid changes the shape of the ribs.
• Refraction changes how the glass bends the photo.
• Fit, and the Size, Distortion and Angle sliders. The preview moves with you.
• Save current keeps your look next to the five recipes.

Made a look you love? Copy recipe puts it on your clipboard as text. Send it to a friend, they click Paste recipe, and they get the same glass on their own photo. Export image… saves the picture itself, if you want it somewhere else.

On a call, you can also just say “open glass wallpaper”.

The glass is drawn on your Mac. Your own photo never leaves it. Koi's five pastel photos come down from koiscribe.com the first time you pick each one, with a little ring filling on its tile while it does.

Glass wallpaper ships in Koi 2.1, next to the video downloader, dictation, call recording and the rest of the notch. More on Glass wallpaper, or how to make a fluted glass wallpaper step by step.
