Effect
What this is
Lightning reveal draws a Lichtenberg figure, the branching pattern a high-voltage discharge burns into wood or glass. Each new branch grows from the tips most likely to break down next, and bright edges in the picture pull the branches along them.
How to use it
- Tap the image to strike from that point.
- Pick a preset, or set forking, jaggedness and glow with the sliders.
- Swap in your own two images, then save a PNG or record a video.

Common questions
Where do my pictures go?
Nowhere. They are opened in your browser and drawn on your graphics card. Nothing is uploaded. The pictures you add stay on this device, in this browser, so the other lab tools can open them too; × on a picture removes it.
