Animusic, Computer Animated Music. This is where you can download some cool music. Aside from that, the reason why I'm posting this website here is because it has a cool, well-made design. My friend and I are looking forward to building our site with a somewhat similar 'coolness'. haha..
Anyway, check their video out, this is fun. What they do is first generate the music, then they make a video that matches the music.
