This is a REAL photograph of REAL mud in Iceland. It is NOT a photo-manipulation or 3D render.
Macabre patterns are formed as volcanic mud bubbles up to the surface in Iceland.
Huge single bubbles were growing and bursting in a volcanic mud pool. The bubbles grew to about 18in (45cm) in diameter then burst suddenly and the heavy mud collapsed in on itself. This image shows the instant of collapse, just a tiny fraction of a second, but incredibly complex shapes are formed as the surface of the bubble breaks up.
