I think this is a good starting concept for an intro. But as previously mentioned i think you need to watch the speed a littlebit. I found it a little too fast. Maybe you could try zooming the camera out also so it's not so close to the balls? I think this would help a great deal. Great idea though mate!
I don't know if you've thought about this but when it comes up with the text maybe the balls/table could fade out onto another image to give the feeling of a logo being formed by the balls motion. Im not sure if that makes sense. If i come across something like it i'll post a link.
