Creeping veins for infection?
I'm likely working on a zombie movie soon. Has anyone tried to do creeping dark veins on a person indicating infection? I can't remember specifically where I've seen this, I'm pretty sure I've seen it somewhere in Star Trek when the Borg used nanoprobes to assimilate. I wonder if the lightning effect would work for this...? Ideally it would be something I could use in conjunction with motion tracking, so if a person's face was moving I could move the veins with it. Ideas?
