Thank you for your help on the design brainstorm session. Below are the mockups for the final site theme based on some of the ideas we talked about.

The design goal is to give this community a distinct look and feel, while still looking like a part of the Stack Exchange network. So I'm not making any layout changes.
The design should also reflect the Android branding. After looking at numerous Android related sites and UI patterns, I've become a big fan of its simplistic and elegant designs.
For the overall look and feel, I want to keep the site airy and clean. The faint honeycomb pattern in the background provides a pleasant noise, but does not get in the way of the content. I also think "Honeycomb" is an appropriate pattern to use because of the Android tablet name.
For the most of the site elements, I went for a "flat" look, polished by hints of translucency. The 3D effects are only reserved for action items such as buttons and widgets.
Of course I'm also using the established green (#A4C639) from the Android branding.
For the typeface, I'm using Droid Sans.
Please let me know what you think. Assuming there are no major design changes, the site will launch very soon.
