What this is
Physarum trails runs a model of Physarum, a slime mould that finds food by laying and following chemical trails. Tens of thousands of agents sense the trail ahead of them, turn toward it and add to it, and the paths settle into a network drawn over the picture.
How to use it
- Tap the image to scatter the agents near that point afresh.
- Pick a preset, or set sensor angle, turn speed and trail decay 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.
