the tutorial I have forgotten the name of

I had watched a tutorial that explained how a sci-fiction short film was made. I can't remember who released it or it's actual file name. it's not Gnomon School – Master Classes 2011 Making Archetype The Short Film with Aaron Sims but generally the same tutorial.

the tutorial involved some sci-fiction movie. most the work was roto. I can remember a scene where a guy is in a washroom with some device coming from his chest. (not the matrix)

please any help would be appreciated
