Well, basically, the story goes like this: I had the render with Raito and the shinigami guys in the background, but I didn't quite know what to do with it. So I started from scratch and experimented with different combinations between the fractals I'd rendered in Apophysis throughout time. It still looked plain, so I added in some clouds, messed around some more with the blending effects and got something relatively decent. It was still kinda empty however, so I brushed in some text [which I later figured would be a nice representation for human laws and such, and given the composition of the wallpaper, it shows that Kira is above them XD]. Then I added some finishing touches in Paint Shop Pro and that was that X-P

Tech. specs: Adobe Photoshop CS2 & Paint Shop Pro 7 / 17 layers / roughly around 4 hours [extraction included].
