Marbling (water painting)

[Karl Robillard]

Make magazine had a posting about paper marbling, which is done by painting on 
water.

You can watch an example of this painting technique on You Tube:

You can read more about it on Galen Berry's The Art of Marbling website:

I don't really follow Krita development closely, so I don't know if you can 
replicate such a style (with some sort of fluid media simulation).
