I've been working on a radio player at http://www.ice.cl (click on one of the channel buttons to open the player).

The player has a rotating volume knob at the top right that as far as I know works only in IE. I have a couple of questions:

- is there any way to make this x-browser compatible?
- does anyone have any suggestions to improve the horrible amount of math I need to do in the DoChange() function?

Any suggestions to improve the overall look/feel graciously accepted also
