Website Header Design

Design Website Header This project is very simple design, but it contains solving User Interface Problem. The Goal is to design Website header which will be over all the Internal Web pages you may look at twitter\facebook at thier header (it's the same in all the pages). The problems need to deal with: 1. Creative Easy of Use Design, the header of the website should allow the users to press on some "services" they intrested to display, for the users there's common things like username, logout option, site logo, help, .. etc but the "services" themself can be diffrenet, more than that, the number of service can change and there are many of them, so i don't think that they can be displayed at the same time. 2. Selection of "Services": as mentioned before the services can be diffrenet, suppose we have "1,2, .. 20" services User A can choose to enable {1,2,5,7} only User B can choose to enable {4,6,7,8} there should be a way how to add\remove service 3. Constant Icons There's some icons which should be displayed seperatly and they are constant among the users like Home\Settings .. etc 4. Coloring We have Login Page and the colors should match the login 5. Footer This contain also the footer which will be like the login page footer .. 6. Size The header size should still be small ! (look at twitter to get the idea) 7. Two modes of the header The header should have two views: A. loged in users (it will display thier selected services .. etc) B. not logged in users it will display minimal things with an option to login 8. This may contain designing some icons also ! - I don't have any idea of the layout of the thing, acttually this i the main over this project you need to find creative simple layout of the things which will be easy to use ! NOTE: We may change some of the details during the work !
