More Coin Questions

Hi all..I have been playing around with the coin effect in the other posts and would like to take this one step further..Is there a way to get the center disk of this graphic to spin in the opposite direction of the outer ring? I know that there might but this also might be pushing it a little bit..

Also what is the code to get this coin to be centered in the middle of this post? I tried the <CENTER>http://www.keithmj.com/coin.gif</CENTER> tags and this doesn't work. Cheers..Keithmj

I attached the .xar file
The graphic should show?
