Nah, Kris is just a big show off with his fountain and all. Wanting to show off all the wee details I suspect!
I don't think you even need to do a flythrough if you don't want to, although I think it's better if you do, even if you take the effects out and just use it to show the modeling then the stills could show all your fancy lighting effects. (Don't think you'd be up for the task of Photoshoping each frame of the flythrough anyway Fraser!
