"End of the World" - Simulation

What would happen if a meteor or comet, about the size of a small moon, hit our planet? When I was in college, I studied the question from the point of view of astronomy and physics. I've even seen a few computer simulations. I have found a great simulation on the internet. The video is in Japanese because it was made by Japanese scientists. It's good because you don't have to understand the narration to see how totally messed up we would be if something like this happened!

Lost Footage of Bruce Lee?

Well, most likely not. But when I first saw it, I was hoping that it was. It's cool. It's someone who looks like Bruce Lee playing ping pong with Nunchucks instead of a paddle! Real or staged or CGI? Well, it's being used to advertise the best Nokia cell phone that I have ever seen. I'd bet that it's not even available state-side yet, considering the commercial is not in English. What do you think? Reel footage or fake? I want to find out more about that phone too.
