Two questions for you:
What does this look like now?
Of what is this the original?
This is DEFINITELY too easy.
a water torrent?
It looks like the Pyrenees from above, but I'm sure its not. More likely some sort of foodstuff?
It looks like water of some sort...
It could be water, but it also looks a bit like a close up of one of those walls or ceilings where the wet plaster has been roughed (don't know the technical term for the effect); or it could be a really tight close up of a verruca on Calum's foot. Such a long-winded way to say "I don't know"
