Are there any apps out there that will let me design evox skins from within Mac OSX (Panther)? I know that I can use PC apps while running Virtual PC, but I was hoping that there was a way to do it from Panther. Any ideas? Thanks.

you don't really need those apps
just download a skin that you like an take a look at the INI file, and screw around with some values. It won't take you long to figure out what's what, and then just create you own
evoX is the easies app to skin for xbox
