Fractal mirror guide

Start

The tool opens with a sample picture already turning in a spiral.

What you need

• A browser with WebGL 2. Current Chrome, Edge, Firefox and Safari have it.
• A picture, if you want your own. Bold shapes and strong colours repeat well.

Your first result

1. Open Fractal mirror. The sample is already a spiral.
2. Press Image A to open a picture, or drop one anywhere on the page.
3. Pick a mode under Mode, or a starting point under Presets.
4. Drag on the picture to move the centre the copies shrink towards.
5. Press Save PNG at the top of the panel to keep it as fractal-mirror.png.

Good to know

• The PNG is the picture as drawn: at most 1200 pixels on its long side, and at most 720 on a phone. It is standard range (SDR).
• Copy puts the same picture on the clipboard, where the browser allows it.
• Auto-rotate is what keeps the pattern moving. Turn it off to hold a frame still before you save.
• Your picture is kept on this device, and every lab tool that takes a picture opens with it, until you press × on its tile.
• On a phone the controls sit in a bar at the bottom of the screen. Tap the bar to open them.
