Help?

Sigh. I have a question, and though it's frequently asked, I can't seem to find the entry. I hit the "Go earlier" button until it disappeared T_T;. I apologize ahead of time, I restored my computer and lost a lot of favorites and apparently I didn't fav it on my other computer while using it.

I'm looking for the tutorial...for this icon (that I don't even have a picture of); it's basically almost like a swirly light texture. Only the circular center part is a clear image, the rest of the background is curved elegantly around the center image.

Could anyone help me find a few tuts. for this? I'm really sorry.
