Does anyone know a good source for 16x16 or 32x32 icons?
I am having a helluva time finding icons that fit my categories well, and my own artistic merit consists of layering photoshop images and using the healing brush (alot  :D )

On that subject, can you use the icons in a Multiple category situation?

Ie I have categorys Perspective, rants, will the standard "name the icon the category" method still work?

Leo's Icon Archive has oodles and oodles and oodles of great icons.  I get lost just looking at everything that's available... creative, colorful stuff in a variety of categories and themes.

Have fun!
