I have been working on these buttons for a while now, and I'm finally happy enough with them to release them to the public. You might notice that they are very slightly inset/beveled into the background. I was going for a high-gloss, graphite, beveled look, similar to what you might see in an application interface. This is only my second set of Photoshop buttons, but the shapes are all vector shapes (except for the dividers) with layer styles applied, so they can be manipulated easily in Photoshop, if you need to customize them. They are intended to be used on a dark background and work best on dark grays.
