rendering engine for "hand drawings"

Hi folks,
if I remember correctly I read an article some time ago about a rendering engine to make renderings which look like you drawn them yourself with a pencil. I was wondering how the name of the rendering engine was and where to get it because I can’t find it anymore.

Thanks for your help.

Are you talking about that “A Scanner Darkly” look? There was a engine but it’s commercial I believe.

I think it looked something like this (attachement)


Oh wow, I’ve never seen that. That’s neat.


jup that was the name, thank you
