Hi guys. This shark animation looks great! I've been trying to use some Blue Screen which was given to me by www.bristolpaint.com so that I could get some people literally walking on the menus and button bars of a website that i'm making. I've had no luck. What software do you use to replace the background? Can the background be animated itself?

My previous attempt at getting an animated person on a website looks at bit strange since I animated him frame by frame... www.swagsandtailsinteriors.co.uk

Thanks
