Dock Icons in the font of House. There are black with white letters and white with black letters.
The preview is a bit deceiving, but for a reason. If you have a solid white or solid black background where the icons are and use that same color, you can have the effect that you see in the middle of the preview. Otherwise, you will see the actual icons as displayed at the top and bottom of the preview.

The A's and O's are a bit funky. They leave an awkward space. If you use the .psd provided, I would suggest typing up to the problematic letter, create a new text layer with that letter, align, rasterize type, merge and tada. You'll need to do some touching up with a 1px pencil. I'm a noob at PS, so you can probably figure out a way to bypass my hassle. (:
