Here is the first post of one of my indigo tests. Maybe you like it…
make a skull with the same settings and you will have a great piece for the gallery! Also, how long did it take to render?
About 7 hours. But I was sleeping so maybe it looked alright already after 3 hours 
Sure, a more interesting Model would help here…
Ok, not a skull…
I found the model on http://www.help3d.com and think it is really nice for a test.
rendertime was about 12 hours but at 1680x1050.
I said skull
