Modeled in MoI, arranged in blender, and rendered in yafaray.
The blur might have been a tad too much for the spheres at the back.
Nice spheres, i love fluorescent. 
Yeah, I’m not too sure how to get rid of DOF noise :\
But everything else is smooth, the new photon-mapping + final-gather is great.
Go to indigo, the mesh lights act better, and the dof is easier to control by using the cursor. You should try using blendigo, as far as I know, it only works good in 2.43

Yeah, I’m fully aware of indigo, and I actually use it for almost everything. But I wanted to try the newer developed yafaray.
Thanks anyway.
oooh nice one
