I rendered a small animation some time ago and didn't had time to share it...
I uploaded it on my vimeo account :)
View it here

There's some framerate errors I messed up in Cinema 4D but that's not important

You can also see a different version here
(the video is under "Animation 3D > 2009 > next button > EDIROL roland")
Le Studio Digital is where I work (learn also) currently its only two people :D

Thanks :)
The monochrome renders are a mix of Ambient Occlusion (wich make nice gradients around geometry) and Cell shading (wich make those outlines) Try to find Ambient Occlusion inside Carrara, I know there's ambient occlusion since Carrara version 5.
You cant fake ambient occlusion in photoshop it will be too difficult and not realistic enough.
