Looks very good Karsten. I'd suggest that you make the background of the Flash (green car) the same color as that of the page (dark gray). When the page first loads up, there is white for the Flash background. You should be able to edit that easy.
Looks good but I did notice that on the main page if I click on the wallpaper menu item the dropdown disapears behind the flash making the last item hard to read.. :-\
