No, that's all just regular effects, Twisted. I guess I'm so used to caustics/refracion and softshadows/GI that I forgot I'd done them here... The subsurface scattering SHOULD be happening in the bottom left one. I used 6 spheres, each slightly smaller than each other and transparent, set to a complex WorldSpace fractal in an attempt to give it more "depth". It didn't work as good as I had hoped... There should have been a much bigger difference in the top left and the bottom left...
