So I like to watch the auto-tuned news videos by The Gregory Brothers on youtube (makers of that Churchill video I mentioned before). They use Katie Couric of CBS News quite a lot. I don't know what it is, whether its the lighting, the make-up, the robot expressions or what, but I think she's a dead ringer for G-Man in Half-Life 2.
A very silly video that I threw together in a few minutes. No attempt at close lip-syncing was made, but some does kinda match up by accident. The video I used is from my favourite machinima video (but heck ,isn't it everyones :) ) "I'm Still Seeing Breen".
