I'd definitely like to see an animated/dynamic WOHD/Fury dashboard theme; if they could make it customizable to some degree, it would be even better... maybe let the user select what team they want to have in the background...

I don't know what they could do for a theme that would be interesting or slightly interactive, but not too obstructing when you're still trying to use the dashboard practically. Maybe they could have it kind of like the Wipeout 3 Prototype stages, with the flat shaded polygons or something
