small flash banner

This banner will be used on a personal website, and is therefore not restricted in size, although it should load as quickly as possible. The .fla file required to edit the banner must become our property upon completion of the project. Here is what we need. The animation starts in black, and then, from the darkness, you begin to see a sun, or a burst of light, emerge from behind a dark spot in the middle of the banner. The effect is supposed to look like an eclipse, but only half of the actual eclipse is seen. You do not see the sun go behind the planet. The Flash banner begins with the sun already behind the planet, fully obscured, and only as the banner begins, does the sun emerge from behind the planet. Once the sun emerges, it rises to the top of the banner, and the planet drops out of sight at the bottom. The sun then simply stays at the top of the banner, surrounded by the darkness of space around it. The banner should be a standard 160X600 skyscrapper ad -- Thanx.
