How about a comic book theme?
Comic book pages for wallpaper. Statues or Avatars of comic book looking heroes (no copyright infringment) maybe a Team Lava Super Hero Squad? Mods and Devs get their own superhero alter ego avatar.
Floor tiles could look like broken pavement (like the Hulk's footprints)
So comic books or super hero theme would interest me.
I absolutely love the asian theme. It would be awesome to have a Geisha waitress like the Irish waitress in Bakery Story!!
Food
Grape Leaves
Bring Las Vegas theme!
