Marco Pavone rendering


I just saw this video on facebook : (this is the work of Marco Pavone).
Here’s a printscreen of it for those who don’t have Facebook (if such people exists loll) :

I wonder how to get the same rendering.
Marco seems to add a colorful background, but before he seems to invert black and white, and after … ? :spin: It seems to have a strong lighting effect around his shapes … is this a cartoon shader or something? I don’t know. That’s why I’m asking you guys! What could be the strategy behind this ? Any idea ?

Thanks you very much !!!

Or should I post this in “Compositing and Post Processing” instead?

EDIT : oh and yes, I asked him but he didn’t answered me.
