Hardcore fan of your state? Or perhaps it just has a pleasing, graphic shape? Or perhaps you're simply looking for new awesome art to hang on your wall? Either way, check out this idea.
This project makes a cool alternative to the family photo gallery, providing some personalization without getting too, uh, family photo gallery.
Plus, the whole idea is made from scratch, so you can customize the look and build things to scale for your space. If you don't dig the white on medium brown look, consider black on natural wood, or turquoise on a walnut stain, etc.
If you're not so much into states, then perhaps go for countries, neighborhoods in your city, or even planets (perfect for the kids' room).
