This is a proof I created over a weekend. It's a made-up games portal and community built around micro-transactions. I focused on the main activities of a normal user on one of these sites, thus the navigation at the top. I used color coding to match windows with their subjects, and the plan for the entire site is to visually inform the user what section they're in and what section each link leads to via color. The colors themselves are bright and playful to go with the game theme, and the site itself is targeted towards a younger audience.
