Patterns in a baking tray covered in grease

I don't always get the washing up done and the other day I left a tray with fat (grease) on it on the kitchen worktop, and the following morning I came to do the washing up and found this pattern on the tray:

Just noticed this post maybe should be in the 'Fractals in nature' forum.
