You access your privacly box with a browser and complete a simple setup process.
Then you see the central page of the privacly box (your personal server): the feed. To get an idea how the feed could look like, please refer to the mockup3_feed.jpg - The feed itself is a timeline in the middle of the screen. Every entry in the timeline is triggered from an installed app or from the privacly box itself ("system-message").
Top left is the main-navigation: Its a combination of navigation and breadcrumb. If you hover over the current breadcrumb (mockup3_feed.jpg) it reveals the whole navigation (mockup3_feed_navigation_hovered.jpg).
Top right is the chat-icon and search-icon. If you hover over them they reveal a search-input-field or the the chat-bar (much like the navigation, just on the right).
If you click in the feed on an app-story you get to the app (free software) itself, but the navbar stays on top and the breadcrumb updates accordingly (mockup3_app_detail.jpg).
The mockup_apps_* images are just for you to show you how the "Apps"-Section will probably look like. You dont have to design them.
I really like the clean and light style of this Bootstrap-Template: http://htmlstream.com/unify/page_home_all.html
In general we do prefer bright, flat, modern, serious designs and metro-colors (green/white, take a look at the attached logo). No dark colors, no playful parts, no clutter.
