Oh man, i wish i had as much free time and boredom as the person that created the video.
You're right, it's quite possible and likely that this is the work of bored, youthful angst, but there could also be a monetization motive, as yet unclear, or (least likely), it could be something else. I've been trying to estimate the amount of work involved, and I imagine 2-3 people with the right skill set could probably make this in a few days - once the plan is there.
Could be material for a high end ARG. Black Watchmen (http://www.blackwatchmen.com/) have done stuff similar to this before, though since that's a game you need to pay to play, people are generally less aware of it. Their coded messages and ciphers are quite extensive.
Could be something like ThisisNotPorn.com
Old site isn't up anymore :(
