I love this clock, but I wish it was cleaner. Have you thought about making your circles vector shapes in Illustrator instead of using photoshop? Right now they're all blurry and wobbly. Just a thought.
To install you probably need to place the xClock folder in the Skins folder inside the Rainmeter. And yes, there is a version with just rotating circles, I just don't remember where I got it. There are also similar GITS clocks, they also look great.
I'm pretty new to editing rainmeter skins. but how to I make the xclock all white? since it has a grayish color, what do i have to edit on the skin notepad to make it all white? sorry.. i'm a n0ob. please help??
