No meaning.
This music "video" is possibly the worst attempt I've seen at trying to be deep, if that be the case. Maybe it's just because I don't like Linkin Park due to the fact that they use the phonetic spelling of Lincoln Park, but I didn't like this video at all.
The backgrounds appeared to be altered in Photoshop with the Cutout filter. And the gears! What was their purpose?
Overall, I'd say: Good job with the animating, but the video made no sense.
