So I was going through CGCookie.com when I came across this: https://cgcookie.com/blender/images/a-vela/
Which was done in the blender internal render engine. It's a brilliant render and the realism blew me away. Being the nutter I am I decided to try something similar in Cycles and see how far I could get. I know that there is a volumetric patch etc. But I wanted to try my own thing and see how close I could get to realism. Turns out not much. Still I wanted to share this so here you go.
Rendered on a Toshiba R830 Satellite (explains the two hour render time for 800 samples). Some small compositor additions and colour tweaking.
