Great Ball with Animated Lighting

This is a new animation focused on animated lighting. There is a 40watt light moving across the scene, and it changes the appearance of the Great Ball subtly. This is the main light source, but there is a little bit of light coming from the HDRI environment (very toned down)
The quality isnt great, for 3 reasons: I limited the render time of each frame to four minutes, my computer isn't powerful, and this is the first time using a .swf animation, so its a bit of an experiment. The file size is 77mb, so it may take a while. sorry for that.
