I think pple might have asked this before but a photo frame or a wall portrait whereby you can slot in your fave FFXIV screenshots and put them up in a picture seems like a pretty cool idea. It could be a shot with your FC members or a memorable dungeon/raid/hunt run. It could even be a wedding picture shot or your fave food.

This would open to more fun in housing and makes things unique to the house/apartment owner too.
