I was thinking of a idea for a challange on a Norwegian blendersite and this is what i came up with. The scene didnt take long to do but the rendersettings was a bit of a hassle because i have never used yafray like this before (yeah, its rendered in yafray).
I did alot of these long renders to see what it would look like, and i liked what i saw. This final render as you see here took 6 hours.
Let me know what you think
