I have been trying to finish up this graphic, but I need a little help with a last effect. If you take a look at the attached pic, you can see a tire. This tire I would like to fade out ( I am not sure if that is the correct technical word for it). Basically, this I would like to make this tire disappear in a clockwise motion to reveal the logo behind it. I think of Pac man when he fades after being tagged by those ghost monsters. Anyhow, I am a bit green so if you can give me a few pointers I'd greatly appreciate it, or if you know a tutorial, please shoot it my way. Thanks in advance!!!
