Just a little mockup for Windows8. A teeny bit based off gaia09.
EDIT: Alrighty, fixed up a lot. There's a taskbar on the bottom left which, next to the application name (in this case, firefox) lists the tabs that are open. The start menu is only for checking updates and such, and Launchy (as seen on the right of the screen) is used in place of the start menu for everything (volume, cp panel, opening apps, etc).
