Hi, everyone,

since I'm try to understand the tools I'm working with (and to satisfy my curosity): how does the framework icons work?

I understand the concept with the background and the negative offsets to adress one small piece of the background. So I expected to find the icons as a grid in the according iu-icons_... png's - but they all seem to be empty respectively contains only one color. So where are the icons?

Thx in advance for your support!
