Nice image. Like the reflectivity effects.

If you do have windows XP, you can download the powertoys off of microsoft's website. One of these is a video screensaver tool, which allows you to put any video as a screensaver. It also comes with the Wallpaper changer, so you can set your wallpaper to change as frequently as 15 min to 1 week. Great for a series of renders.

save time will be increased dramatically if your hard drive is fragged. (well, for windows anyway)

bangin'

it might look slick because it's shiny: try decreasing reflectivity
