The "Revolution" of speakers?

Just saw this on YouTube. I thought the only fun you could have with old hard drives was target practice, but it looks like some people are much more creative. If you find this interesting you have passed over the geeky side of life. If you think it's a waste of time, (you may be right) but you have not crossed over yet.
If you want to build your own set follow the link after the video. (this may get you that uber geek title)
