ok here is an avi of the animation, it's really dark cause there were no lights apart from the default light and it's also really "busy" (you'll see what I mean)

It's still in the preliminary stages but I'd really like some feedback.

Cheers
Alan

Ps Is the video ok for everyone else? I'm getting really jerky playback for some reason!
