As you might know I'm currently working on an editor for Village Defense. It has this toolbar in it with all kinds of buttons. Point is I need to put some proper glyphs on it, so I can see more easily what these buttons do.
Now I could make them myself, but I figured there're probably lots of em already. Ah well, turns out after a bit of googling, getting a nice set of different (preferably 16/32 bit color) icons isn't all that easy.

So I was wondering does any of you know where to find free glyphs or icons?

Thanks
