Now that you've turned your Mac into a PC, turn it into a Mac again

So you've done the formerly impossible and unnecessary: installed Winders on a Mac. Cool, best of both worlds. But there you are, staring at that awful primary color, jumbo crayon, sickly plasticky XP theme. Yeah, you could use one of the many mods featured on Download Squad (please, feel free). Or you could turn your XP rig back into a Mac. At least, you can make XP look a lot more like a Mac. Engadget did this nearly 2 years ago, although Aqua-Soft is still updating their content. Or why not go old school with an OS 9 flavor? Ah, that's better.
