Need some direction

I’ve been tasked with created a flash gauge that adjusts itself based on outside parameters.
Also adding to the problems is that they want it to look like a speedometer.
I’ve never had to develop this kind of thing before. I’ve never done ActionScript that accesses outside parameters and I’ve never done circular motion (for the speedometer needle).

And they also need me to use IceFaces parameters:
[FONT=&quot]<ice:outputMedia player=“flash” source="/media/ICEfaces_Skyscraper_120x600.swf" style=“width:120px;height:600px;”>[/FONT]
[FONT=&quot] <f:param name=“play” value=“true”/>[/FONT]
[FONT=&quot] <f:param name=“menu” value=“true”/>[/FONT]
[FONT=&quot] </ice:outputMedia>[/FONT]

I’m not looking for anyone to build this for me, just some direction of where to look for the pieces I could use to construct this.

Thanks a lot!
