That video was very awesome. I wish they would form that into a full game.

Anyway, I never experienced the effect in any video game, but the last time I felt weirded out when when I saw The Polar Express back when it came out in 2004. I couldn't enjoy the movie because I felt queasy looking at it the whole time. I didn't feel as if I was going to throw up my popcorn any time soon, but still. I knew what I was seeing what computer generated characters with motion capturing, but my mind kept on subconsciously insisting it was all real. I think the mental tug of war is what gave me that feeling.

Anyway, I think that's the only time I even been profoundly effected by the Uncanny Valley Effect. Otherwise, I just say, "That looks kind of funky," and move on.
